-Synopsis
---------
-
-The Mercurial system uses a set of configuration files to control
-aspects of its behavior.
-
-Files
------
-
-Mercurial reads configuration data from several files, if they exist.
-The names of these files depend on the system on which Mercurial is
-installed. ``*.rc`` files from a single directory are read in
-alphabetical order, later ones overriding earlier ones. Where multiple
-paths are given below, settings from earlier paths override later
-ones.
-
-| (Unix, Windows) ``<repo>/.hg/hgrc``
-
-    Per-repository configuration options that only apply in a
-    particular repository. This file is not version-controlled, and
-    will not get transferred during a "clone" operation. Options in
-    this file override options in all other configuration files. On
-    Unix, most of this file will be ignored if it doesn't belong to a
-    trusted user or to a trusted group. See the documentation for the
-    trusted_ section below for more details.
-
-| (Unix) ``$HOME/.hgrc``
-| (Windows) ``%USERPROFILE%\.hgrc``
-| (Windows) ``%USERPROFILE%\Mercurial.ini``
-| (Windows) ``%HOME%\.hgrc``
-| (Windows) ``%HOME%\Mercurial.ini``
-
-    Per-user configuration file(s), for the user running Mercurial. On
-    Windows 9x, ``%HOME%`` is replaced by ``%APPDATA%``. Options in these
-    files apply to all Mercurial commands executed by this user in any
-    directory. Options in these files override per-system and per-installation
-    options.
-
-| (Unix) ``/etc/mercurial/hgrc``
-| (Unix) ``/etc/mercurial/hgrc.d/*.rc``
-
-    Per-system configuration files, for the system on which Mercurial
-    is running. Options in these files apply to all Mercurial commands
-    executed by any user in any directory. Options in these files
-    override per-installation options.
-
-| (Unix) ``<install-root>/etc/mercurial/hgrc``
-| (Unix) ``<install-root>/etc/mercurial/hgrc.d/*.rc``
-
-    Per-installation configuration files, searched for in the
-    directory where Mercurial is installed. ``<install-root>`` is the
-    parent directory of the **hg** executable (or symlink) being run. For
-    example, if installed in ``/shared/tools/bin/hg``, Mercurial will look
-    in ``/shared/tools/etc/mercurial/hgrc``. Options in these files apply
-    to all Mercurial commands executed by any user in any directory.
-
-| (Windows) ``<install-dir>\Mercurial.ini``
-| (Windows) ``<install-dir>\hgrc.d\*.rc``
-| (Windows) ``HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial``
-
-    Per-installation/system configuration files, for the system on
-    which Mercurial is running. Options in these files apply to all
-    Mercurial commands executed by any user in any directory. Registry
-    keys contain PATH-like strings, every part of which must reference
-    a ``Mercurial.ini`` file or be a directory where ``*.rc`` files will
-    be read.  Mercurial checks each of these locations in the specified
-    order until one or more configuration files are detected.  If the
-    pywin32 extensions are not installed, Mercurial will only look for
-    site-wide configuration in ``C:\Mercurial\Mercurial.ini``.
-
-Syntax
-------
-
-A configuration file consists of sections, led by a ``[section]`` header
-and followed by ``name = value`` entries (sometimes called
-``configuration keys``)::
-
-    [spam]
-    eggs=ham
-    green=
-       eggs
-
-Each line contains one entry. If the lines that follow are indented,
-they are treated as continuations of that entry. Leading whitespace is
-removed from values. Empty lines are skipped. Lines beginning with
-``#`` or ``;`` are ignored and may be used to provide comments.
-
-Configuration keys can be set multiple times, in which case mercurial
-will use the value that was configured last. As an example::
-
-    [spam]
-    eggs=large
-    ham=serrano
-    eggs=small
-
-This would set the configuration key named ``eggs`` to ``small``.
-
-It is also possible to define a section multiple times. A section can
-be redefined on the same and/or on different hgrc files. For example::
-
-    [foo]
-    eggs=large
-    ham=serrano
-    eggs=small
-
-    [bar]
-    eggs=ham
-    green=
-       eggs
-
-    [foo]
-    ham=prosciutto
-    eggs=medium
-    bread=toasted
-
-This would set the ``eggs``, ``ham``, and ``bread`` configuration keys
-of the ``foo`` section to ``medium``, ``prosciutto``, and ``toasted``,
-respectively. As you can see there only thing that matters is the last
-value that was set for each of the configuration keys.
-
-If a configuration key is set multiple times in different
-configuration files the final value will depend on the order in which
-the different configuration files are read, with settings from earlier
-paths overriding later ones as described on the ``Files`` section
-above.
-
-A line of the form ``%include file`` will include ``file`` into the
-current configuration file. The inclusion is recursive, which means
-that included files can include other files. Filenames are relative to
-the configuration file in which the ``%include`` directive is found.
-Environment variables and ``~user`` constructs are expanded in
-``file``. This lets you do something like::
-
-  %include ~/.hgrc.d/$HOST.rc
-
-to include a different configuration file on each computer you use.
-
-A line with ``%unset name`` will remove ``name`` from the current
-section, if it has been set previously.
-
-The values are either free-form text strings, lists of text strings,
-or Boolean values. Boolean values can be set to true using any of "1",
-"yes", "true", or "on" and to false using "0", "no", "false", or "off"
-(all case insensitive).
-
-List values are separated by whitespace or comma, except when values are
-placed in double quotation marks::
-
-  allow_read = "John Doe, PhD", brian, betty
-
-Quotation marks can be escaped by prefixing them with a backslash. Only
-quotation marks at the beginning of a word is counted as a quotation
-(e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).
-
-Sections
---------
-
-This section describes the different sections that may appear in a
-Mercurial "hgrc" file, the purpose of each section, its possible keys,
-and their possible values.
-
-``alias``
-"""""""""
-Defines command aliases.
-Aliases allow you to define your own commands in terms of other
-commands (or aliases), optionally including arguments.
-
-Alias definitions consist of lines of the form::
-
-    <alias> = <command> [<argument]...
-
-For example, this definition::
-
-    latest = log --limit 5
-
-creates a new command ``latest`` that shows only the five most recent
-changesets. You can define subsequent aliases using earlier ones::
-
-    stable5 = latest -b stable
-
-.. note:: It is possible to create aliases with the same names as
-   existing commands, which will then override the original
-   definitions. This is almost always a bad idea!
-
-
-``auth``
-""""""""
-
-Authentication credentials for HTTP authentication. This section
-allows you to store usernames and passwords for use when logging
-*into* HTTP servers. See the web_ configuration section if you want to
-configure *who* can login to your HTTP server.
-
-Each line has the following format::
-
-    <name>.<argument> = <value>
-
-where ``<name>`` is used to group arguments into authentication
-entries. Example::
-
-    foo.prefix = hg.intevation.org/mercurial
-    foo.username = foo
-    foo.password = bar
-    foo.schemes = http https
-
-    bar.prefix = secure.example.org
-    bar.key = path/to/file.key
-    bar.cert = path/to/file.cert
-    bar.schemes = https
-
-Supported arguments:
-
-``prefix``
-    Either ``*`` or a URI prefix with or without the scheme part.
-    The authentication entry with the longest matching prefix is used
-    (where ``*`` matches everything and counts as a match of length
-    1). If the prefix doesn't include a scheme, the match is performed
-    against the URI with its scheme stripped as well, and the schemes
-    argument, q.v., is then subsequently consulted.
-``username``
-    Optional. Username to authenticate with. If not given, and the
-    remote site requires basic or digest authentication, the user will
-    be prompted for it. Environment variables are expanded in the
-    username letting you do ``foo.username = $USER``.
-``password``
-    Optional. Password to authenticate with. If not given, and the
-    remote site requires basic or digest authentication, the user
-    will be prompted for it.
-``key``
-    Optional. PEM encoded client certificate key file. Environment
-    variables are expanded in the filename.
-``cert``
-    Optional. PEM encoded client certificate chain file. Environment
-    variables are expanded in the filename.
-``schemes``
-    Optional. Space separated list of URI schemes to use this
-    authentication entry with. Only used if the prefix doesn't include
-    a scheme. Supported schemes are http and https. They will match
-    static-http and static-https respectively, as well.
-    Default: https.
-
-If no suitable authentication entry is found, the user is prompted
-for credentials as usual if required by the remote.
-
-
-``decode/encode``
-"""""""""""""""""
-Filters for transforming files on checkout/checkin. This would
-typically be used for newline processing or other
-localization/canonicalization of files.
-
-Filters consist of a filter pattern followed by a filter command.
-Filter patterns are globs by default, rooted at the repository root.
-For example, to match any file ending in ``.txt`` in the root
-directory only, use the pattern ``*.txt``. To match any file ending
-in ``.c`` anywhere in the repository, use the pattern ``**.c``.
-For each file only the first matching filter applies.
-
-The filter command can start with a specifier, either ``pipe:`` or
-``tempfile:``. If no specifier is given, ``pipe:`` is used by default.
-
-A ``pipe:`` command must accept data on stdin and return the transformed
-data on stdout.
-
-Pipe example::
-
-  [encode]
-  # uncompress gzip files on checkin to improve delta compression
-  # note: not necessarily a good idea, just an example
-  *.gz = pipe: gunzip
-
-  [decode]
-  # recompress gzip files when writing them to the working dir (we
-  # can safely omit "pipe:", because it's the default)
-  *.gz = gzip
-
-A ``tempfile:`` command is a template. The string ``INFILE`` is replaced
-with the name of a temporary file that contains the data to be
-filtered by the command. The string ``OUTFILE`` is replaced with the name
-of an empty temporary file, where the filtered data must be written by
-the command.
-
-.. note:: The tempfile mechanism is recommended for Windows systems,
-   where the standard shell I/O redirection operators often have
-   strange effects and may corrupt the contents of your files.
-
-This filter mechanism is used internally by the ``eol`` extension to
-translate line ending characters between Windows (CRLF) and Unix (LF)
-format. We suggest you use the ``eol`` extension for convenience.
-
-
-``defaults``
-""""""""""""
-
-(defaults are deprecated. Don't use them. Use aliases instead)
-
-Use the ``[defaults]`` section to define command defaults, i.e. the
-default options/arguments to pass to the specified commands.
-
-The following example makes :hg:`log` run in verbose mode, and
-:hg:`status` show only the modified files, by default::
-
-  [defaults]
-  log = -v
-  status = -m
-
-The actual commands, instead of their aliases, must be used when
-defining command defaults. The command defaults will also be applied
-to the aliases of the commands defined.
-
-
-``diff``
-""""""""
-
-Settings used when displaying diffs. Everything except for ``unified`` is a
-Boolean and defaults to False.
-
-``git``
-    Use git extended diff format.
-``nodates``
-    Don't include dates in diff headers.
-``showfunc``
-    Show which function each change is in.
-``ignorews``
-    Ignore white space when comparing lines.
-``ignorewsamount``
-    Ignore changes in the amount of white space.
-``ignoreblanklines``
-    Ignore changes whose lines are all blank.
-``unified``
-    Number of lines of context to show.
-
-``email``
-"""""""""
-Settings for extensions that send email messages.
-
-``from``
-    Optional. Email address to use in "From" header and SMTP envelope
-    of outgoing messages.
-``to``
-    Optional. Comma-separated list of recipients' email addresses.
-``cc``
-    Optional. Comma-separated list of carbon copy recipients'
-    email addresses.
-``bcc``
-    Optional. Comma-separated list of blind carbon copy recipients'
-    email addresses.
-``method``
-    Optional. Method to use to send email messages. If value is ``smtp``
-    (default), use SMTP (see the SMTP_ section for configuration).
-    Otherwise, use as name of program to run that acts like sendmail
-    (takes ``-f`` option for sender, list of recipients on command line,
-    message on stdin). Normally, setting this to ``sendmail`` or
-    ``/usr/sbin/sendmail`` is enough to use sendmail to send messages.
-``charsets``
-    Optional. Comma-separated list of character sets considered
-    convenient for recipients. Addresses, headers, and parts not
-    containing patches of outgoing messages will be encoded in the
-    first character set to which conversion from local encoding
-    (``$HGENCODING``, ``ui.fallbackencoding``) succeeds. If correct
-    conversion fails, the text in question is sent as is. Defaults to
-    empty (explicit) list.
-
-    Order of outgoing email character sets:
-
-    1. ``us-ascii``: always first, regardless of settings
-    2. ``email.charsets``: in order given by user
-    3. ``ui.fallbackencoding``: if not in email.charsets
-    4. ``$HGENCODING``: if not in email.charsets
-    5. ``utf-8``: always last, regardless of settings
-
-Email example::
-
-  [email]
-  from = Joseph User <joe.user at example.com>
-  method = /usr/sbin/sendmail
-  # charsets for western Europeans
-  # us-ascii, utf-8 omitted, as they are tried first and last
-  charsets = iso-8859-1, iso-8859-15, windows-1252
-
-
-``extensions``
-""""""""""""""
-
-Mercurial has an extension mechanism for adding new features. To
-enable an extension, create an entry for it in this section.
-
-If you know that the extension is already in Python's search path,
-you can give the name of the module, followed by ``=``, with nothing
-after the ``=``.
-
-Otherwise, give a name that you choose, followed by ``=``, followed by
-the path to the ``.py`` file (including the file name extension) that
-defines the extension.
-
-To explicitly disable an extension that is enabled in an hgrc of
-broader scope, prepend its path with ``!``, as in ``foo = !/ext/path``
-or ``foo = !`` when path is not supplied.
-
-Example for ``~/.hgrc``::
-
-  [extensions]
-  # (the mq extension will get loaded from Mercurial's path)
-  mq =
-  # (this extension will get loaded from the file specified)
-  myfeature = ~/.hgext/myfeature.py
-
-
-``hostfingerprints``
-""""""""""""""""""""
-
-Fingerprints of the certificates of known HTTPS servers.
-A HTTPS connection to a server with a fingerprint configured here will
-only succeed if the servers certificate matches the fingerprint.
-This is very similar to how ssh known hosts works.
-The fingerprint is the SHA-1 hash value of the DER encoded certificate.
-The CA chain and web.cacerts is not used for servers with a fingerprint.
-
-For example::
-
-    [hostfingerprints]
-    hg.intevation.org = 38:76:52:7c:87:26:9a:8f:4a:f8:d3:de:08:45:3b:ea:d6:4b:ee:cc
-
-This feature is only supported when using Python 2.6 or later.
-
-
-``format``
-""""""""""
-
-``usestore``
-    Enable or disable the "store" repository format which improves
-    compatibility with systems that fold case or otherwise mangle
-    filenames. Enabled by default. Disabling this option will allow
-    you to store longer filenames in some situations at the expense of
-    compatibility and ensures that the on-disk format of newly created
-    repositories will be compatible with Mercurial before version 0.9.4.
-
-``usefncache``
-    Enable or disable the "fncache" repository format which enhances
-    the "store" repository format (which has to be enabled to use
-    fncache) to allow longer filenames and avoids using Windows
-    reserved names, e.g. "nul". Enabled by default. Disabling this
-    option ensures that the on-disk format of newly created
-    repositories will be compatible with Mercurial before version 1.1.
-
-``dotencode``
-    Enable or disable the "dotencode" repository format which enhances
-    the "fncache" repository format (which has to be enabled to use
-    dotencode) to avoid issues with filenames starting with ._ on
-    Mac OS X and spaces on Windows. Enabled by default. Disabling this
-    option ensures that the on-disk format of newly created
-    repositories will be compatible with Mercurial before version 1.7.
-
-``merge-patterns``
-""""""""""""""""""
-
-This section specifies merge tools to associate with particular file
-patterns. Tools matched here will take precedence over the default
-merge tool. Patterns are globs by default, rooted at the repository
-root.
-
-Example::
-
-  [merge-patterns]
-  **.c = kdiff3
-  **.jpg = myimgmerge
-
-``merge-tools``
-"""""""""""""""
-
-This section configures external merge tools to use for file-level
-merges.
-
-Example ``~/.hgrc``::
-
-  [merge-tools]
-  # Override stock tool location
-  kdiff3.executable = ~/bin/kdiff3
-  # Specify command line
-  kdiff3.args = $base $local $other -o $output
-  # Give higher priority
-  kdiff3.priority = 1
-
-  # Define new tool
-  myHtmlTool.args = -m $local $other $base $output
-  myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
-  myHtmlTool.priority = 1
-
-Supported arguments:
-
-``priority``
-  The priority in which to evaluate this tool.
-  Default: 0.
-``executable``
-  Either just the name of the executable or its pathname.  On Windows,
-  the path can use environment variables with ${ProgramFiles} syntax.
-  Default: the tool name.
-``args``
-  The arguments to pass to the tool executable. You can refer to the
-  files being merged as well as the output file through these
-  variables: ``$base``, ``$local``, ``$other``, ``$output``.
-  Default: ``$local $base $other``
-``premerge``
-  Attempt to run internal non-interactive 3-way merge tool before
-  launching external tool.  Options are ``true``, ``false``, or ``keep``
-  to leave markers in the file if the premerge fails.
-  Default: True
-``binary``
-  This tool can merge binary files. Defaults to False, unless tool
-  was selected by file pattern match.
-``symlink``
-  This tool can merge symlinks. Defaults to False, even if tool was
-  selected by file pattern match.
-``check``
-  A list of merge success-checking options:
-
-  ``changed``
-    Ask whether merge was successful when the merged file shows no changes.
-  ``conflicts``
-    Check whether there are conflicts even though the tool reported success.
-  ``prompt``
-    Always prompt for merge success, regardless of success reported by tool.
-
-``checkchanged``
-  True is equivalent to ``check = changed``.
-  Default: False
-``checkconflicts``
-  True is equivalent to ``check = conflicts``.
-  Default: False
-``fixeol``
-  Attempt to fix up EOL changes caused by the merge tool.
-  Default: False
-``gui``
-  This tool requires a graphical interface to run. Default: False
-``regkey``
-  Windows registry key which describes install location of this
-  tool. Mercurial will search for this key first under
-  ``HKEY_CURRENT_USER`` and then under ``HKEY_LOCAL_MACHINE``.
-  Default: None
-``regkeyalt``
-  An alternate Windows registry key to try if the first key is not
-  found.  The alternate key uses the same ``regname`` and ``regappend``
-  semantics of the primary key.  The most common use for this key
-  is to search for 32bit applications on 64bit operating systems.
-  Default: None
-``regname``
-  Name of value to read from specified registry key. Defaults to the
-  unnamed (default) value.
-``regappend``
-  String to append to the value read from the registry, typically
-  the executable name of the tool.
-  Default: None
-
-
-``hooks``
-"""""""""
-Commands or Python functions that get automatically executed by
-various actions such as starting or finishing a commit. Multiple
-hooks can be run for the same action by appending a suffix to the
-action. Overriding a site-wide hook can be done by changing its
-value or setting it to an empty string.
-
-Example ``.hg/hgrc``::
-
-  [hooks]
-  # update working directory after adding changesets
-  changegroup.update = hg update
-  # do not use the site-wide hook
-  incoming =
-  incoming.email = /my/email/hook
-  incoming.autobuild = /my/build/hook
-
-Most hooks are run with environment variables set that give useful
-additional information. For each hook below, the environment
-variables it is passed are listed with names of the form ``$HG_foo``.
-
-``changegroup``
-  Run after a changegroup has been added via push, pull or unbundle.
-  ID of the first new changeset is in ``$HG_NODE``. URL from which
-  changes came is in ``$HG_URL``.
-``commit``
-  Run after a changeset has been created in the local repository. ID
-  of the newly created changeset is in ``$HG_NODE``. Parent changeset
-  IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
-``incoming``
-  Run after a changeset has been pulled, pushed, or unbundled into
-  the local repository. The ID of the newly arrived changeset is in
-  ``$HG_NODE``. URL that was source of changes came is in ``$HG_URL``.
-``outgoing``
-  Run after sending changes from local repository to another. ID of
-  first changeset sent is in ``$HG_NODE``. Source of operation is in
-  ``$HG_SOURCE``; see "preoutgoing" hook for description.
-``post-<command>``
-  Run after successful invocations of the associated command. The
-  contents of the command line are passed as ``$HG_ARGS`` and the result
-  code in ``$HG_RESULT``. Parsed command line arguments are passed as 
-  ``$HG_PATS`` and ``$HG_OPTS``. These contain string representations of
-  the python data internally passed to <command>. ``$HG_OPTS`` is a 
-  dictionary of options (with unspecified options set to their defaults).
-  ``$HG_PATS`` is a list of arguments. Hook failure is ignored.
-``pre-<command>``
-  Run before executing the associated command. The contents of the
-  command line are passed as ``$HG_ARGS``. Parsed command line arguments
-  are passed as ``$HG_PATS`` and ``$HG_OPTS``. These contain string
-  representations of the data internally passed to <command>. ``$HG_OPTS``
-  is a  dictionary of options (with unspecified options set to their
-  defaults). ``$HG_PATS`` is a list of arguments. If the hook returns 
-  failure, the command doesn't execute and Mercurial returns the failure
-  code.
-``prechangegroup``
-  Run before a changegroup is added via push, pull or unbundle. Exit
-  status 0 allows the changegroup to proceed. Non-zero status will
-  cause the push, pull or unbundle to fail. URL from which changes
-  will come is in ``$HG_URL``.
-``precommit``
-  Run before starting a local commit. Exit status 0 allows the
-  commit to proceed. Non-zero status will cause the commit to fail.
-  Parent changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
-``preoutgoing``
-  Run before collecting changes to send from the local repository to
-  another. Non-zero status will cause failure. This lets you prevent
-  pull over HTTP or SSH. Also prevents against local pull, push
-  (outbound) or bundle commands, but not effective, since you can
-  just copy files instead then. Source of operation is in
-  ``$HG_SOURCE``. If "serve", operation is happening on behalf of remote
-  SSH or HTTP repository. If "push", "pull" or "bundle", operation
-  is happening on behalf of repository on same system.
-``pretag``
-  Run before creating a tag. Exit status 0 allows the tag to be
-  created. Non-zero status will cause the tag to fail. ID of
-  changeset to tag is in ``$HG_NODE``. Name of tag is in ``$HG_TAG``. Tag is
-  local if ``$HG_LOCAL=1``, in repository if ``$HG_LOCAL=0``.
-``pretxnchangegroup``
-  Run after a changegroup has been added via push, pull or unbundle,
-  but before the transaction has been committed. Changegroup is
-  visible to hook program. This lets you validate incoming changes
-  before accepting them. Passed the ID of the first new changeset in
-  ``$HG_NODE``. Exit status 0 allows the transaction to commit. Non-zero
-  status will cause the transaction to be rolled back and the push,
-  pull or unbundle will fail. URL that was source of changes is in
-  ``$HG_URL``.
-``pretxncommit``
-  Run after a changeset has been created but the transaction not yet
-  committed. Changeset is visible to hook program. This lets you
-  validate commit message and changes. Exit status 0 allows the
-  commit to proceed. Non-zero status will cause the transaction to
-  be rolled back. ID of changeset is in ``$HG_NODE``. Parent changeset
-  IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
-``preupdate``
-  Run before updating the working directory. Exit status 0 allows
-  the update to proceed. Non-zero status will prevent the update.
-  Changeset ID of first new parent is in ``$HG_PARENT1``. If merge, ID
-  of second new parent is in ``$HG_PARENT2``.
-``tag``
-  Run after a tag is created. ID of tagged changeset is in ``$HG_NODE``.
-  Name of tag is in ``$HG_TAG``. Tag is local if ``$HG_LOCAL=1``, in
-  repository if ``$HG_LOCAL=0``.
-``update``
-  Run after updating the working directory. Changeset ID of first
-  new parent is in ``$HG_PARENT1``. If merge, ID of second new parent is
-  in ``$HG_PARENT2``. If the update succeeded, ``$HG_ERROR=0``. If the
-  update failed (e.g. because conflicts not resolved), ``$HG_ERROR=1``.
-
-.. note:: It is generally better to use standard hooks rather than the
-   generic pre- and post- command hooks as they are guaranteed to be
-   called in the appropriate contexts for influencing transactions.
-   Also, hooks like "commit" will be called in all contexts that
-   generate a commit (e.g. tag) and not just the commit command.
-
-.. note:: Environment variables with empty values may not be passed to
-   hooks on platforms such as Windows. As an example, ``$HG_PARENT2``
-   will have an empty value under Unix-like platforms for non-merge
-   changesets, while it will not be available at all under Windows.
-
-The syntax for Python hooks is as follows::
-
-  hookname = python:modulename.submodule.callable
-  hookname = python:/path/to/python/module.py:callable
-
-Python hooks are run within the Mercurial process. Each hook is
-called with at least three keyword arguments: a ui object (keyword
-``ui``), a repository object (keyword ``repo``), and a ``hooktype``
-keyword that tells what kind of hook is used. Arguments listed as
-environment variables above are passed as keyword arguments, with no
-``HG_`` prefix, and names in lower case.
-
-If a Python hook returns a "true" value or raises an exception, this
-is treated as a failure.
-
-
-``http_proxy``
-""""""""""""""
-Used to access web-based Mercurial repositories through a HTTP
-proxy.
-
-``host``
-    Host name and (optional) port of the proxy server, for example
-    "myproxy:8000".
-``no``
-    Optional. Comma-separated list of host names that should bypass
-    the proxy.
-``passwd``
-    Optional. Password to authenticate with at the proxy server.
-``user``
-    Optional. User name to authenticate with at the proxy server.
-``always``
-    Optional. Always use the proxy, even for localhost and any entries
-    in ``http_proxy.no``. True or False. Default: False.
-
-``smtp``
-""""""""
-Configuration for extensions that need to send email messages.
-
-``host``
-    Host name of mail server, e.g. "mail.example.com".
-``port``
-    Optional. Port to connect to on mail server. Default: 25.
-``tls``
-    Optional. Method to enable TLS when connecting to mail server: starttls,
-    smtps or none. Default: none.
-``username``
-    Optional. User name for authenticating with the SMTP server.
-    Default: none.
-``password``
-    Optional. Password for authenticating with the SMTP server. If not
-    specified, interactive sessions will prompt the user for a
-    password; non-interactive sessions will fail. Default: none.
-``local_hostname``
-    Optional. It's the hostname that the sender can use to identify
-    itself to the MTA.
-
-
-``patch``
-"""""""""
-Settings used when applying patches, for instance through the 'import'
-command or with Mercurial Queues extension.
-
-``eol``
-    When set to 'strict' patch content and patched files end of lines
-    are preserved. When set to ``lf`` or ``crlf``, both files end of
-    lines are ignored when patching and the result line endings are
-    normalized to either LF (Unix) or CRLF (Windows). When set to
-    ``auto``, end of lines are again ignored while patching but line
-    endings in patched files are normalized to their original setting
-    on a per-file basis. If target file does not exist or has no end
-    of line, patch line endings are preserved.
-    Default: strict.
-
-
-``paths``
-"""""""""
-Assigns symbolic names to repositories. The left side is the
-symbolic name, and the right gives the directory or URL that is the
-location of the repository. Default paths can be declared by setting
-the following entries.
-
-``default``
-    Directory or URL to use when pulling if no source is specified.
-    Default is set to repository from which the current repository was
-    cloned.
-``default-push``
-    Optional. Directory or URL to use when pushing if no destination
-    is specified.
-
-
-``profiling``
-"""""""""""""
-Specifies profiling format and file output. In this section
-description, 'profiling data' stands for the raw data collected
-during profiling, while 'profiling report' stands for a statistical
-text report generated from the profiling data. The profiling is done
-using lsprof.
-
-``format``
-    Profiling format.
-    Default: text.
-
-    ``text``
-      Generate a profiling report. When saving to a file, it should be
-      noted that only the report is saved, and the profiling data is
-      not kept.
-    ``kcachegrind``
-      Format profiling data for kcachegrind use: when saving to a
-      file, the generated file can directly be loaded into
-      kcachegrind.
-``output``
-    File path where profiling data or report should be saved. If the
-    file exists, it is replaced. Default: None, data is printed on
-    stderr
-
-``server``
-""""""""""
-Controls generic server settings.
-
-``uncompressed``
-    Whether to allow clients to clone a repository using the
-    uncompressed streaming protocol. This transfers about 40% more
-    data than a regular clone, but uses less memory and CPU on both
-    server and client. Over a LAN (100 Mbps or better) or a very fast
-    WAN, an uncompressed streaming clone is a lot faster (~10x) than a
-    regular clone. Over most WAN connections (anything slower than
-    about 6 Mbps), uncompressed streaming is slower, because of the
-    extra data transfer overhead. This mode will also temporarily hold
-    the write lock while determining what data to transfer.
-    Default is True.
-
-``validate``
-    Whether to validate the completeness of pushed changesets by
-    checking that all new file revisions specified in manifests are
-    present. Default is False.
-
-``subpaths``
-""""""""""""
-Defines subrepositories source locations rewriting rules of the form::
-
-    <pattern> = <replacement>
-
-Where ``pattern`` is a regular expression matching the source and
-``replacement`` is the replacement string used to rewrite it. Groups
-can be matched in ``pattern`` and referenced in ``replacements``. For
-instance::
-
-    http://server/(.*)-hg/ = http://hg.server/\1/
-
-rewrites ``http://server/foo-hg/`` into ``http://hg.server/foo/``.
-
-All patterns are applied in definition order.
-
-``trusted``
-"""""""""""
-
-Mercurial will not use the settings in the
-``.hg/hgrc`` file from a repository if it doesn't belong to a trusted
-user or to a trusted group, as various hgrc features allow arbitrary
-commands to be run. This issue is often encountered when configuring
-hooks or extensions for shared repositories or servers. However,
-the web interface will use some safe settings from the ``[web]``
-section.
-
-This section specifies what users and groups are trusted. The
-current user is always trusted. To trust everybody, list a user or a
-group with name ``*``. These settings must be placed in an
-*already-trusted file* to take effect, such as ``$HOME/.hgrc`` of the
-user or service running Mercurial.
-
-``users``
-  Comma-separated list of trusted users.
-``groups``
-  Comma-separated list of trusted groups.
-
-
-``ui``
-""""""
-
-User interface controls.
-
-``archivemeta``
-    Whether to include the .hg_archival.txt file containing meta data
-    (hashes for the repository base and for tip) in archives created
-    by the :hg:`archive` command or downloaded via hgweb.
-    Default is True.
-``askusername``
-    Whether to prompt for a username when committing. If True, and
-    neither ``$HGUSER`` nor ``$EMAIL`` has been specified, then the user will
-    be prompted to enter a username. If no username is entered, the
-    default ``USER at HOST`` is used instead.
-    Default is False.
-``commitsubrepos``
-    Whether to commit modified subrepositories when committing the
-    parent repository. If False and one subrepository has uncommitted
-    changes, abort the commit.
-    Default is True.
-``debug``
-    Print debugging information. True or False. Default is False.
-``editor``
-    The editor to use during a commit. Default is ``$EDITOR`` or ``vi``.
-``fallbackencoding``
-    Encoding to try if it's not possible to decode the changelog using
-    UTF-8. Default is ISO-8859-1.
-``ignore``
-    A file to read per-user ignore patterns from. This file should be
-    in the same format as a repository-wide .hgignore file. This
-    option supports hook syntax, so if you want to specify multiple
-    ignore files, you can do so by setting something like
-    ``ignore.other = ~/.hgignore2``. For details of the ignore file
-    format, see the |hgignore(5)|_ man page.
-``interactive``
-    Allow to prompt the user. True or False. Default is True.
-``logtemplate``
-    Template string for commands that print changesets.
-``merge``
-    The conflict resolution program to use during a manual merge.
-    For more information on merge tools see :hg:`help merge-tools`.
-    For configuring merge tools see the merge-tools_ section.
-``patch``
-    command to use to apply patches. Look for ``gpatch`` or ``patch`` in
-    PATH if unset.
-``quiet``
-    Reduce the amount of output printed. True or False. Default is False.
-``remotecmd``
-    remote command to use for clone/push/pull operations. Default is ``hg``.
-``report_untrusted``
-    Warn if a ``.hg/hgrc`` file is ignored due to not being owned by a
-    trusted user or group. True or False. Default is True.
-``slash``
-    Display paths using a slash (``/``) as the path separator. This
-    only makes a difference on systems where the default path
-    separator is not the slash character (e.g. Windows uses the
-    backslash character (``\``)).
-    Default is False.
-``ssh``
-    command to use for SSH connections. Default is ``ssh``.
-``strict``
-    Require exact command names, instead of allowing unambiguous
-    abbreviations. True or False. Default is False.
-``style``
-    Name of style to use for command output.
-``timeout``
-    The timeout used when a lock is held (in seconds), a negative value
-    means no timeout. Default is 600.
-``traceback``
-    Mercurial always prints a traceback when an unknown exception
-    occurs. Setting this to True will make Mercurial print a traceback
-    on all exceptions, even those recognized by Mercurial (such as
-    IOError or MemoryError). Default is False.
-``username``
-    The committer of a changeset created when running "commit".
-    Typically a person's name and email address, e.g. ``Fred Widget
-    <fred at example.com>``. Default is ``$EMAIL`` or ``username at hostname``. If
-    the username in hgrc is empty, it has to be specified manually or
-    in a different hgrc file (e.g. ``$HOME/.hgrc``, if the admin set
-    ``username =``  in the system hgrc). Environment variables in the
-    username are expanded.
-``verbose``
-    Increase the amount of output printed. True or False. Default is False.
-
-
-``web``
-"""""""
-
-Web interface configuration. The settings in this section apply to
-both the builtin webserver (started by :hg:`serve`) and the script you
-run through a webserver (``hgweb.cgi`` and the derivatives for FastCGI
-and WSGI).
-
-The Mercurial webserver does no authentication (it does not prompt for
-usernames and passwords to validate *who* users are), but it does do
-authorization (it grants or denies access for *authenticated users*
-based on settings in this section). You must either configure your
-webserver to do authentication for you, or disable the authorization
-checks.
-
-For a quick setup in a trusted environment, e.g., a private LAN, where
-you want it to accept pushes from anybody, you can use the following
-command line::
-
-    $ hg --config web.allow_push=* --config web.push_ssl=False serve
-
-Note that this will allow anybody to push anything to the server and
-that this should not be used for public servers.
-
-The full set of options is:
-
-``accesslog``
-    Where to output the access log. Default is stdout.
-``address``
-    Interface address to bind to. Default is all.
-``allow_archive``
-    List of archive format (bz2, gz, zip) allowed for downloading.
-    Default is empty.
-``allowbz2``
-    (DEPRECATED) Whether to allow .tar.bz2 downloading of repository
-    revisions.
-    Default is False.
-``allowgz``
-    (DEPRECATED) Whether to allow .tar.gz downloading of repository
-    revisions.
-    Default is False.
-``allowpull``
-    Whether to allow pulling from the repository. Default is True.
-``allow_push``
-    Whether to allow pushing to the repository. If empty or not set,
-    push is not allowed. If the special value ``*``, any remote user can
-    push, including unauthenticated users. Otherwise, the remote user
-    must have been authenticated, and the authenticated user name must
-    be present in this list. The contents of the allow_push list are
-    examined after the deny_push list.
-``allow_read``
-    If the user has not already been denied repository access due to
-    the contents of deny_read, this list determines whether to grant
-    repository access to the user. If this list is not empty, and the
-    user is unauthenticated or not present in the list, then access is
-    denied for the user. If the list is empty or not set, then access
-    is permitted to all users by default. Setting allow_read to the
-    special value ``*`` is equivalent to it not being set (i.e. access
-    is permitted to all users). The contents of the allow_read list are
-    examined after the deny_read list.
-``allowzip``
-    (DEPRECATED) Whether to allow .zip downloading of repository
-    revisions. Default is False. This feature creates temporary files.
-``baseurl``
-    Base URL to use when publishing URLs in other locations, so
-    third-party tools like email notification hooks can construct
-    URLs. Example: ``http://hgserver/repos/``.
-``cacerts``
-    Path to file containing a list of PEM encoded certificate
-    authority certificates. Environment variables and ``~user``
-    constructs are expanded in the filename. If specified on the
-    client, then it will verify the identity of remote HTTPS servers
-    with these certificates. The form must be as follows::
-
-        -----BEGIN CERTIFICATE-----
-        ... (certificate in base64 PEM encoding) ...
-        -----END CERTIFICATE-----
-        -----BEGIN CERTIFICATE-----
-        ... (certificate in base64 PEM encoding) ...
-        -----END CERTIFICATE-----
-
-    This feature is only supported when using Python 2.6 or later. If you wish
-    to use it with earlier versions of Python, install the backported
-    version of the ssl library that is available from
-    ``http://pypi.python.org``.
-
-    You can use OpenSSL's CA certificate file if your platform has one.
-    On most Linux systems this will be ``/etc/ssl/certs/ca-certificates.crt``.
-    Otherwise you will have to generate this file manually.
-
-    To disable SSL verification temporarily, specify ``--insecure`` from
-    command line.
-``contact``
-    Name or email address of the person in charge of the repository.
-    Defaults to ui.username or ``$EMAIL`` or "unknown" if unset or empty.
-``deny_push``
-    Whether to deny pushing to the repository. If empty or not set,
-    push is not denied. If the special value ``*``, all remote users are
-    denied push. Otherwise, unauthenticated users are all denied, and
-    any authenticated user name present in this list is also denied. The
-    contents of the deny_push list are examined before the allow_push list.
-``deny_read``
-    Whether to deny reading/viewing of the repository. If this list is
-    not empty, unauthenticated users are all denied, and any
-    authenticated user name present in this list is also denied access to
-    the repository. If set to the special value ``*``, all remote users
-    are denied access (rarely needed ;). If deny_read is empty or not set,
-    the determination of repository access depends on the presence and
-    content of the allow_read list (see description). If both
-    deny_read and allow_read are empty or not set, then access is
-    permitted to all users by default. If the repository is being
-    served via hgwebdir, denied users will not be able to see it in
-    the list of repositories. The contents of the deny_read list have
-    priority over (are examined before) the contents of the allow_read
-    list.
-``descend``
-    hgwebdir indexes will not descend into subdirectories. Only repositories
-    directly in the current path will be shown (other repositories are still
-    available from the index corresponding to their containing path).
-``description``
-    Textual description of the repository's purpose or contents.
-    Default is "unknown".
-``encoding``
-    Character encoding name. Default is the current locale charset.
-    Example: "UTF-8"
-``errorlog``
-    Where to output the error log. Default is stderr.
-``hidden``
-    Whether to hide the repository in the hgwebdir index.
-    Default is False.
-``ipv6``
-    Whether to use IPv6. Default is False.
-``name``
-    Repository name to use in the web interface. Default is current
-    working directory.
-``maxchanges``
-    Maximum number of changes to list on the changelog. Default is 10.
-``maxfiles``
-    Maximum number of files to list per changeset. Default is 10.
-``port``
-    Port to listen on. Default is 8000.
-``prefix``
-    Prefix path to serve from. Default is '' (server root).
-``push_ssl``
-    Whether to require that inbound pushes be transported over SSL to
-    prevent password sniffing. Default is True.
-``staticurl``
-    Base URL to use for static files. If unset, static files (e.g. the
-    hgicon.png favicon) will be served by the CGI script itself. Use
-    this setting to serve them directly with the HTTP server.
-    Example: ``http://hgserver/static/``.
-``stripes``
-    How many lines a "zebra stripe" should span in multiline output.
-    Default is 1; set to 0 to disable.
-``style``
-    Which template map style to use.
-``templates``
-    Where to find the HTML templates. Default is install path.

+
+Synopsis
+--------
+
+The Mercurial system uses a set of configuration files to control
+aspects of its behavior.
+
+Files
+-----
+
+Mercurial reads configuration data from several files, if they exist.
+The names of these files depend on the system on which Mercurial is
+installed. ``*.rc`` files from a single directory are read in
+alphabetical order, later ones overriding earlier ones. Where multiple
+paths are given below, settings from earlier paths override later
+ones.
+
+| (Unix, Windows) ``<repo>/.hg/hgrc``
+
+    Per-repository configuration options that only apply in a
+    particular repository. This file is not version-controlled, and
+    will not get transferred during a "clone" operation. Options in
+    this file override options in all other configuration files. On
+    Unix, most of this file will be ignored if it doesn't belong to a
+    trusted user or to a trusted group. See the documentation for the
+    trusted_ section below for more details.
+
+| (Unix) ``$HOME/.hgrc``
+| (Windows) ``%USERPROFILE%\.hgrc``
+| (Windows) ``%USERPROFILE%\Mercurial.ini``
+| (Windows) ``%HOME%\.hgrc``
+| (Windows) ``%HOME%\Mercurial.ini``
+
+    Per-user configuration file(s), for the user running Mercurial. On
+    Windows 9x, ``%HOME%`` is replaced by ``%APPDATA%``. Options in these
+    files apply to all Mercurial commands executed by this user in any
+    directory. Options in these files override per-system and per-installation
+    options.
+
+| (Unix) ``/etc/mercurial/hgrc``
+| (Unix) ``/etc/mercurial/hgrc.d/*.rc``
+
+    Per-system configuration files, for the system on which Mercurial
+    is running. Options in these files apply to all Mercurial commands
+    executed by any user in any directory. Options in these files
+    override per-installation options.
+
+| (Unix) ``<install-root>/etc/mercurial/hgrc``
+| (Unix) ``<install-root>/etc/mercurial/hgrc.d/*.rc``
+
+    Per-installation configuration files, searched for in the
+    directory where Mercurial is installed. ``<install-root>`` is the
+    parent directory of the **hg** executable (or symlink) being run. For
+    example, if installed in ``/shared/tools/bin/hg``, Mercurial will look
+    in ``/shared/tools/etc/mercurial/hgrc``. Options in these files apply
+    to all Mercurial commands executed by any user in any directory.
+
+| (Windows) ``<install-dir>\Mercurial.ini``
+| (Windows) ``<install-dir>\hgrc.d\*.rc``
+| (Windows) ``HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial``
+
+    Per-installation/system configuration files, for the system on
+    which Mercurial is running. Options in these files apply to all
+    Mercurial commands executed by any user in any directory. Registry
+    keys contain PATH-like strings, every part of which must reference
+    a ``Mercurial.ini`` file or be a directory where ``*.rc`` files will
+    be read.  Mercurial checks each of these locations in the specified
+    order until one or more configuration files are detected.  If the
+    pywin32 extensions are not installed, Mercurial will only look for
+    site-wide configuration in ``C:\Mercurial\Mercurial.ini``.
+
+Syntax
+------
+
+A configuration file consists of sections, led by a ``[section]`` header
+and followed by ``name = value`` entries (sometimes called
+``configuration keys``)::
+
+    [spam]
+    eggs=ham
+    green=
+       eggs
+
+Each line contains one entry. If the lines that follow are indented,
+they are treated as continuations of that entry. Leading whitespace is
+removed from values. Empty lines are skipped. Lines beginning with
+``#`` or ``;`` are ignored and may be used to provide comments.
+
+Configuration keys can be set multiple times, in which case mercurial
+will use the value that was configured last. As an example::
+
+    [spam]
+    eggs=large
+    ham=serrano
+    eggs=small
+
+This would set the configuration key named ``eggs`` to ``small``.
+
+It is also possible to define a section multiple times. A section can
+be redefined on the same and/or on different hgrc files. For example::
+
+    [foo]
+    eggs=large
+    ham=serrano
+    eggs=small
+
+    [bar]
+    eggs=ham
+    green=
+       eggs
+
+    [foo]
+    ham=prosciutto
+    eggs=medium
+    bread=toasted
+
+This would set the ``eggs``, ``ham``, and ``bread`` configuration keys
+of the ``foo`` section to ``medium``, ``prosciutto``, and ``toasted``,
+respectively. As you can see there only thing that matters is the last
+value that was set for each of the configuration keys.
+
+If a configuration key is set multiple times in different
+configuration files the final value will depend on the order in which
+the different configuration files are read, with settings from earlier
+paths overriding later ones as described on the ``Files`` section
+above.
+
+A line of the form ``%include file`` will include ``file`` into the
+current configuration file. The inclusion is recursive, which means
+that included files can include other files. Filenames are relative to
+the configuration file in which the ``%include`` directive is found.
+Environment variables and ``~user`` constructs are expanded in
+``file``. This lets you do something like::
+
+  %include ~/.hgrc.d/$HOST.rc
+
+to include a different configuration file on each computer you use.
+
+A line with ``%unset name`` will remove ``name`` from the current
+section, if it has been set previously.
+
+The values are either free-form text strings, lists of text strings,
+or Boolean values. Boolean values can be set to true using any of "1",
+"yes", "true", or "on" and to false using "0", "no", "false", or "off"
+(all case insensitive).
+
+List values are separated by whitespace or comma, except when values are
+placed in double quotation marks::
+
+  allow_read = "John Doe, PhD", brian, betty
+
+Quotation marks can be escaped by prefixing them with a backslash. Only
+quotation marks at the beginning of a word is counted as a quotation
+(e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).
+
+Sections
+--------
+
+This section describes the different sections that may appear in a
+Mercurial "hgrc" file, the purpose of each section, its possible keys,
+and their possible values.
+
+``alias``
+"""""""""
+Defines command aliases.
+Aliases allow you to define your own commands in terms of other
+commands (or aliases), optionally including arguments.
+
+Alias definitions consist of lines of the form::
+
+    <alias> = <command> [<argument]...
+
+For example, this definition::
+
+    latest = log --limit 5
+
+creates a new command ``latest`` that shows only the five most recent
+changesets. You can define subsequent aliases using earlier ones::
+
+    stable5 = latest -b stable
+
+.. note:: It is possible to create aliases with the same names as
+   existing commands, which will then override the original
+   definitions. This is almost always a bad idea!
+
+
+``auth``
+""""""""
+
+Authentication credentials for HTTP authentication. This section
+allows you to store usernames and passwords for use when logging
+*into* HTTP servers. See the web_ configuration section if you want to
+configure *who* can login to your HTTP server.
+
+Each line has the following format::
+
+    <name>.<argument> = <value>
+
+where ``<name>`` is used to group arguments into authentication
+entries. Example::
+
+    foo.prefix = hg.intevation.org/mercurial
+    foo.username = foo
+    foo.password = bar
+    foo.schemes = http https
+
+    bar.prefix = secure.example.org
+    bar.key = path/to/file.key
+    bar.cert = path/to/file.cert
+    bar.schemes = https
+
+Supported arguments:
+
+``prefix``
+    Either ``*`` or a URI prefix with or without the scheme part.
+    The authentication entry with the longest matching prefix is used
+    (where ``*`` matches everything and counts as a match of length
+    1). If the prefix doesn't include a scheme, the match is performed
+    against the URI with its scheme stripped as well, and the schemes
+    argument, q.v., is then subsequently consulted.
+``username``
+    Optional. Username to authenticate with. If not given, and the
+    remote site requires basic or digest authentication, the user will
+    be prompted for it. Environment variables are expanded in the
+    username letting you do ``foo.username = $USER``.
+``password``
+    Optional. Password to authenticate with. If not given, and the
+    remote site requires basic or digest authentication, the user
+    will be prompted for it.
+``key``
+    Optional. PEM encoded client certificate key file. Environment
+    variables are expanded in the filename.
+``cert``
+    Optional. PEM encoded client certificate chain file. Environment
+    variables are expanded in the filename.
+``schemes``
+    Optional. Space separated list of URI schemes to use this
+    authentication entry with. Only used if the prefix doesn't include
+    a scheme. Supported schemes are http and https. They will match
+    static-http and static-https respectively, as well.
+    Default: https.
+
+If no suitable authentication entry is found, the user is prompted
+for credentials as usual if required by the remote.
+
+
+``decode/encode``
+"""""""""""""""""
+Filters for transforming files on checkout/checkin. This would
+typically be used for newline processing or other
+localization/canonicalization of files.
+
+Filters consist of a filter pattern followed by a filter command.
+Filter patterns are globs by default, rooted at the repository root.
+For example, to match any file ending in ``.txt`` in the root
+directory only, use the pattern ``*.txt``. To match any file ending
+in ``.c`` anywhere in the repository, use the pattern ``**.c``.
+For each file only the first matching filter applies.
+
+The filter command can start with a specifier, either ``pipe:`` or
+``tempfile:``. If no specifier is given, ``pipe:`` is used by default.
+
+A ``pipe:`` command must accept data on stdin and return the transformed
+data on stdout.
+
+Pipe example::
+
+  [encode]
+  # uncompress gzip files on checkin to improve delta compression
+  # note: not necessarily a good idea, just an example
+  *.gz = pipe: gunzip
+
+  [decode]
+  # recompress gzip files when writing them to the working dir (we
+  # can safely omit "pipe:", because it's the default)
+  *.gz = gzip
+
+A ``tempfile:`` command is a template. The string ``INFILE`` is replaced
+with the name of a temporary file that contains the data to be
+filtered by the command. The string ``OUTFILE`` is replaced with the name
+of an empty temporary file, where the filtered data must be written by
+the command.
+
+.. note:: The tempfile mechanism is recommended for Windows systems,
+   where the standard shell I/O redirection operators often have
+   strange effects and may corrupt the contents of your files.
+
+This filter mechanism is used internally by the ``eol`` extension to
+translate line ending characters between Windows (CRLF) and Unix (LF)
+format. We suggest you use the ``eol`` extension for convenience.
+
+
+``defaults``
+""""""""""""
+
+(defaults are deprecated. Don't use them. Use aliases instead)
+
+Use the ``[defaults]`` section to define command defaults, i.e. the
+default options/arguments to pass to the specified commands.
+
+The following example makes :hg:`log` run in verbose mode, and
+:hg:`status` show only the modified files, by default::
+
+  [defaults]
+  log = -v
+  status = -m
+
+The actual commands, instead of their aliases, must be used when
+defining command defaults. The command defaults will also be applied
+to the aliases of the commands defined.
+
+
+``diff``
+""""""""
+
+Settings used when displaying diffs. Everything except for ``unified`` is a
+Boolean and defaults to False.
+
+``git``
+    Use git extended diff format.
+``nodates``
+    Don't include dates in diff headers.
+``showfunc``
+    Show which function each change is in.
+``ignorews``
+    Ignore white space when comparing lines.
+``ignorewsamount``
+    Ignore changes in the amount of white space.
+``ignoreblanklines``
+    Ignore changes whose lines are all blank.
+``unified``
+    Number of lines of context to show.
+
+``email``
+"""""""""
+Settings for extensions that send email messages.
+
+``from``
+    Optional. Email address to use in "From" header and SMTP envelope
+    of outgoing messages.
+``to``
+    Optional. Comma-separated list of recipients' email addresses.
+``cc``
+    Optional. Comma-separated list of carbon copy recipients'
+    email addresses.
+``bcc``
+    Optional. Comma-separated list of blind carbon copy recipients'
+    email addresses.
+``method``
+    Optional. Method to use to send email messages. If value is ``smtp``
+    (default), use SMTP (see the SMTP_ section for configuration).
+    Otherwise, use as name of program to run that acts like sendmail
+    (takes ``-f`` option for sender, list of recipients on command line,
+    message on stdin). Normally, setting this to ``sendmail`` or
+    ``/usr/sbin/sendmail`` is enough to use sendmail to send messages.
+``charsets``
+    Optional. Comma-separated list of character sets considered
+    convenient for recipients. Addresses, headers, and parts not
+    containing patches of outgoing messages will be encoded in the
+    first character set to which conversion from local encoding
+    (``$HGENCODING``, ``ui.fallbackencoding``) succeeds. If correct
+    conversion fails, the text in question is sent as is. Defaults to
+    empty (explicit) list.
+
+    Order of outgoing email character sets:
+
+    1. ``us-ascii``: always first, regardless of settings
+    2. ``email.charsets``: in order given by user
+    3. ``ui.fallbackencoding``: if not in email.charsets
+    4. ``$HGENCODING``: if not in email.charsets
+    5. ``utf-8``: always last, regardless of settings
+
+Email example::
+
+  [email]
+  from = Joseph User <joe.user at example.com>
+  method = /usr/sbin/sendmail
+  # charsets for western Europeans
+  # us-ascii, utf-8 omitted, as they are tried first and last
+  charsets = iso-8859-1, iso-8859-15, windows-1252
+
+
+``extensions``
+""""""""""""""
+
+Mercurial has an extension mechanism for adding new features. To
+enable an extension, create an entry for it in this section.
+
+If you know that the extension is already in Python's search path,
+you can give the name of the module, followed by ``=``, with nothing
+after the ``=``.
+
+Otherwise, give a name that you choose, followed by ``=``, followed by
+the path to the ``.py`` file (including the file name extension) that
+defines the extension.
+
+To explicitly disable an extension that is enabled in an hgrc of
+broader scope, prepend its path with ``!``, as in ``foo = !/ext/path``
+or ``foo = !`` when path is not supplied.
+
+Example for ``~/.hgrc``::
+
+  [extensions]
+  # (the mq extension will get loaded from Mercurial's path)
+  mq =
+  # (this extension will get loaded from the file specified)
+  myfeature = ~/.hgext/myfeature.py
+
+
+``hostfingerprints``
+""""""""""""""""""""
+
+Fingerprints of the certificates of known HTTPS servers.
+A HTTPS connection to a server with a fingerprint configured here will
+only succeed if the servers certificate matches the fingerprint.
+This is very similar to how ssh known hosts works.
+The fingerprint is the SHA-1 hash value of the DER encoded certificate.
+The CA chain and web.cacerts is not used for servers with a fingerprint.
+
+For example::
+
+    [hostfingerprints]
+    hg.intevation.org = 38:76:52:7c:87:26:9a:8f:4a:f8:d3:de:08:45:3b:ea:d6:4b:ee:cc
+
+This feature is only supported when using Python 2.6 or later.
+
+
+``format``
+""""""""""
+
+``usestore``
+    Enable or disable the "store" repository format which improves
+    compatibility with systems that fold case or otherwise mangle
+    filenames. Enabled by default. Disabling this option will allow
+    you to store longer filenames in some situations at the expense of
+    compatibility and ensures that the on-disk format of newly created
+    repositories will be compatible with Mercurial before version 0.9.4.
+
+``usefncache``
+    Enable or disable the "fncache" repository format which enhances
+    the "store" repository format (which has to be enabled to use
+    fncache) to allow longer filenames and avoids using Windows
+    reserved names, e.g. "nul". Enabled by default. Disabling this
+    option ensures that the on-disk format of newly created
+    repositories will be compatible with Mercurial before version 1.1.
+
+``dotencode``
+    Enable or disable the "dotencode" repository format which enhances
+    the "fncache" repository format (which has to be enabled to use
+    dotencode) to avoid issues with filenames starting with ._ on
+    Mac OS X and spaces on Windows. Enabled by default. Disabling this
+    option ensures that the on-disk format of newly created
+    repositories will be compatible with Mercurial before version 1.7.
+
+``merge-patterns``
+""""""""""""""""""
+
+This section specifies merge tools to associate with particular file
+patterns. Tools matched here will take precedence over the default
+merge tool. Patterns are globs by default, rooted at the repository
+root.
+
+Example::
+
+  [merge-patterns]
+  **.c = kdiff3
+  **.jpg = myimgmerge
+
+``merge-tools``
+"""""""""""""""
+
+This section configures external merge tools to use for file-level
+merges.
+
+Example ``~/.hgrc``::
+
+  [merge-tools]
+  # Override stock tool location
+  kdiff3.executable = ~/bin/kdiff3
+  # Specify command line
+  kdiff3.args = $base $local $other -o $output
+  # Give higher priority
+  kdiff3.priority = 1
+
+  # Define new tool
+  myHtmlTool.args = -m $local $other $base $output
+  myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
+  myHtmlTool.priority = 1
+
+Supported arguments:
+
+``priority``
+  The priority in which to evaluate this tool.
+  Default: 0.
+``executable``
+  Either just the name of the executable or its pathname.  On Windows,
+  the path can use environment variables with ${ProgramFiles} syntax.
+  Default: the tool name.
+``args``
+  The arguments to pass to the tool executable. You can refer to the
+  files being merged as well as the output file through these
+  variables: ``$base``, ``$local``, ``$other``, ``$output``.
+  Default: ``$local $base $other``
+``premerge``
+  Attempt to run internal non-interactive 3-way merge tool before
+  launching external tool.  Options are ``true``, ``false``, or ``keep``
+  to leave markers in the file if the premerge fails.
+  Default: True
+``binary``
+  This tool can merge binary files. Defaults to False, unless tool
+  was selected by file pattern match.
+``symlink``
+  This tool can merge symlinks. Defaults to False, even if tool was
+  selected by file pattern match.
+``check``
+  A list of merge success-checking options:
+
+  ``changed``
+    Ask whether merge was successful when the merged file shows no changes.
+  ``conflicts``
+    Check whether there are conflicts even though the tool reported success.
+  ``prompt``
+    Always prompt for merge success, regardless of success reported by tool.
+
+``checkchanged``
+  True is equivalent to ``check = changed``.
+  Default: False
+``checkconflicts``
+  True is equivalent to ``check = conflicts``.
+  Default: False
+``fixeol``
+  Attempt to fix up EOL changes caused by the merge tool.
+  Default: False
+``gui``
+  This tool requires a graphical interface to run. Default: False
+``regkey``
+  Windows registry key which describes install location of this
+  tool. Mercurial will search for this key first under
+  ``HKEY_CURRENT_USER`` and then under ``HKEY_LOCAL_MACHINE``.
+  Default: None
+``regkeyalt``
+  An alternate Windows registry key to try if the first key is not
+  found.  The alternate key uses the same ``regname`` and ``regappend``
+  semantics of the primary key.  The most common use for this key
+  is to search for 32bit applications on 64bit operating systems.
+  Default: None
+``regname``
+  Name of value to read from specified registry key. Defaults to the
+  unnamed (default) value.
+``regappend``
+  String to append to the value read from the registry, typically
+  the executable name of the tool.
+  Default: None
+
+
+``hooks``
+"""""""""
+Commands or Python functions that get automatically executed by
+various actions such as starting or finishing a commit. Multiple
+hooks can be run for the same action by appending a suffix to the
+action. Overriding a site-wide hook can be done by changing its
+value or setting it to an empty string.
+
+Example ``.hg/hgrc``::
+
+  [hooks]
+  # update working directory after adding changesets
+  changegroup.update = hg update
+  # do not use the site-wide hook
+  incoming =
+  incoming.email = /my/email/hook
+  incoming.autobuild = /my/build/hook
+
+Most hooks are run with environment variables set that give useful
+additional information. For each hook below, the environment
+variables it is passed are listed with names of the form ``$HG_foo``.
+
+``changegroup``
+  Run after a changegroup has been added via push, pull or unbundle.
+  ID of the first new changeset is in ``$HG_NODE``. URL from which
+  changes came is in ``$HG_URL``.
+``commit``
+  Run after a changeset has been created in the local repository. ID
+  of the newly created changeset is in ``$HG_NODE``. Parent changeset
+  IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
+``incoming``
+  Run after a changeset has been pulled, pushed, or unbundled into
+  the local repository. The ID of the newly arrived changeset is in
+  ``$HG_NODE``. URL that was source of changes came is in ``$HG_URL``.
+``outgoing``
+  Run after sending changes from local repository to another. ID of
+  first changeset sent is in ``$HG_NODE``. Source of operation is in
+  ``$HG_SOURCE``; see "preoutgoing" hook for description.
+``post-<command>``
+  Run after successful invocations of the associated command. The
+  contents of the command line are passed as ``$HG_ARGS`` and the result
+  code in ``$HG_RESULT``. Parsed command line arguments are passed as 
+  ``$HG_PATS`` and ``$HG_OPTS``. These contain string representations of
+  the python data internally passed to <command>. ``$HG_OPTS`` is a 
+  dictionary of options (with unspecified options set to their defaults).
+  ``$HG_PATS`` is a list of arguments. Hook failure is ignored.
+``pre-<command>``
+  Run before executing the associated command. The contents of the
+  command line are passed as ``$HG_ARGS``. Parsed command line arguments
+  are passed as ``$HG_PATS`` and ``$HG_OPTS``. These contain string
+  representations of the data internally passed to <command>. ``$HG_OPTS``
+  is a  dictionary of options (with unspecified options set to their
+  defaults). ``$HG_PATS`` is a list of arguments. If the hook returns 
+  failure, the command doesn't execute and Mercurial returns the failure
+  code.
+``prechangegroup``
+  Run before a changegroup is added via push, pull or unbundle. Exit
+  status 0 allows the changegroup to proceed. Non-zero status will
+  cause the push, pull or unbundle to fail. URL from which changes
+  will come is in ``$HG_URL``.
+``precommit``
+  Run before starting a local commit. Exit status 0 allows the
+  commit to proceed. Non-zero status will cause the commit to fail.
+  Parent changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
+``preoutgoing``
+  Run before collecting changes to send from the local repository to
+  another. Non-zero status will cause failure. This lets you prevent
+  pull over HTTP or SSH. Also prevents against local pull, push
+  (outbound) or bundle commands, but not effective, since you can
+  just copy files instead then. Source of operation is in
+  ``$HG_SOURCE``. If "serve", operation is happening on behalf of remote
+  SSH or HTTP repository. If "push", "pull" or "bundle", operation
+  is happening on behalf of repository on same system.
+``pretag``
+  Run before creating a tag. Exit status 0 allows the tag to be
+  created. Non-zero status will cause the tag to fail. ID of
+  changeset to tag is in ``$HG_NODE``. Name of tag is in ``$HG_TAG``. Tag is
+  local if ``$HG_LOCAL=1``, in repository if ``$HG_LOCAL=0``.
+``pretxnchangegroup``
+  Run after a changegroup has been added via push, pull or unbundle,
+  but before the transaction has been committed. Changegroup is
+  visible to hook program. This lets you validate incoming changes
+  before accepting them. Passed the ID of the first new changeset in
+  ``$HG_NODE``. Exit status 0 allows the transaction to commit. Non-zero
+  status will cause the transaction to be rolled back and the push,
+  pull or unbundle will fail. URL that was source of changes is in
+  ``$HG_URL``.
+``pretxncommit``
+  Run after a changeset has been created but the transaction not yet
+  committed. Changeset is visible to hook program. This lets you
+  validate commit message and changes. Exit status 0 allows the
+  commit to proceed. Non-zero status will cause the transaction to
+  be rolled back. ID of changeset is in ``$HG_NODE``. Parent changeset
+  IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
+``preupdate``
+  Run before updating the working directory. Exit status 0 allows
+  the update to proceed. Non-zero status will prevent the update.
+  Changeset ID of first new parent is in ``$HG_PARENT1``. If merge, ID
+  of second new parent is in ``$HG_PARENT2``.
+``tag``
+  Run after a tag is created. ID of tagged changeset is in ``$HG_NODE``.
+  Name of tag is in ``$HG_TAG``. Tag is local if ``$HG_LOCAL=1``, in
+  repository if ``$HG_LOCAL=0``.
+``update``
+  Run after updating the working directory. Changeset ID of first
+  new parent is in ``$HG_PARENT1``. If merge, ID of second new parent is
+  in ``$HG_PARENT2``. If the update succeeded, ``$HG_ERROR=0``. If the
+  update failed (e.g. because conflicts not resolved), ``$HG_ERROR=1``.
+
+.. note:: It is generally better to use standard hooks rather than the
+   generic pre- and post- command hooks as they are guaranteed to be
+   called in the appropriate contexts for influencing transactions.
+   Also, hooks like "commit" will be called in all contexts that
+   generate a commit (e.g. tag) and not just the commit command.
+
+.. note:: Environment variables with empty values may not be passed to
+   hooks on platforms such as Windows. As an example, ``$HG_PARENT2``
+   will have an empty value under Unix-like platforms for non-merge
+   changesets, while it will not be available at all under Windows.
+
+The syntax for Python hooks is as follows::
+
+  hookname = python:modulename.submodule.callable
+  hookname = python:/path/to/python/module.py:callable
+
+Python hooks are run within the Mercurial process. Each hook is
+called with at least three keyword arguments: a ui object (keyword
+``ui``), a repository object (keyword ``repo``), and a ``hooktype``
+keyword that tells what kind of hook is used. Arguments listed as
+environment variables above are passed as keyword arguments, with no
+``HG_`` prefix, and names in lower case.
+
+If a Python hook returns a "true" value or raises an exception, this
+is treated as a failure.
+
+
+``http_proxy``
+""""""""""""""
+Used to access web-based Mercurial repositories through a HTTP
+proxy.
+
+``host``
+    Host name and (optional) port of the proxy server, for example
+    "myproxy:8000".
+``no``
+    Optional. Comma-separated list of host names that should bypass
+    the proxy.
+``passwd``
+    Optional. Password to authenticate with at the proxy server.
+``user``
+    Optional. User name to authenticate with at the proxy server.
+``always``
+    Optional. Always use the proxy, even for localhost and any entries
+    in ``http_proxy.no``. True or False. Default: False.
+
+``smtp``

+Configuration for extensions that need to send email messages.
+
+``host``
+    Host name of mail server, e.g. "mail.example.com".
+``port``
+    Optional. Port to connect to on mail server. Default: 25.
+``tls``
+    Optional. Method to enable TLS when connecting to mail server: starttls,
+    smtps or none. Default: none.
+``username``
+    Optional. User name for authenticating with the SMTP server.
+    Default: none.
+``password``
+    Optional. Password for authenticating with the SMTP server. If not
+    specified, interactive sessions will prompt the user for a
+    password; non-interactive sessions will fail. Default: none.
+``local_hostname``
+    Optional. It's the hostname that the sender can use to identify
+    itself to the MTA.
+
+
+``patch``
+"""""""""
+Settings used when applying patches, for instance through the 'import'
+command or with Mercurial Queues extension.
+
+``eol``
+    When set to 'strict' patch content and patched files end of lines
+    are preserved. When set to ``lf`` or ``crlf``, both files end of
+    lines are ignored when patching and the result line endings are
+    normalized to either LF (Unix) or CRLF (Windows). When set to
+    ``auto``, end of lines are again ignored while patching but line
+    endings in patched files are normalized to their original setting
+    on a per-file basis. If target file does not exist or has no end
+    of line, patch line endings are preserved.
+    Default: strict.
+
+
+``paths``
+"""""""""
+Assigns symbolic names to repositories. The left side is the
+symbolic name, and the right gives the directory or URL that is the
+location of the repository. Default paths can be declared by setting

+
+``default``
+    Directory or URL to use when pulling if no source is specified.
+    Default is set to repository from which the current repository was

+``profiling``
+"""""""""""""
+Specifies profiling format and file output. In this section
+description, 'profiling data' stands for the raw data collected
+during profiling, while 'profiling report' stands for a statistical
+text report generated from the profiling data. The profiling is done
+using lsprof.
+
+``format``
+    Profiling format.
+    Default: text.
+
+    ``text``
+      Generate a profiling report. When saving to a file, it should be
+      noted that only the report is saved, and the profiling data is
+      not kept.
+    ``kcachegrind``
+      Format profiling data for kcachegrind use: when saving to a
+      file, the generated file can directly be loaded into
+      kcachegrind.
+``output``
+    File path where profiling data or report should be saved. If the
+    file exists, it is replaced. Default: None, data is printed on
+    stderr
+
+``server``
+""""""""""
+Controls generic server settings.
+
+``uncompressed``
+    Whether to allow clients to clone a repository using the
+    uncompressed streaming protocol. This transfers about 40% more
+    data than a regular clone, but uses less memory and CPU on both
+    server and client. Over a LAN (100 Mbps or better) or a very fast
+    WAN, an uncompressed streaming clone is a lot faster (~10x) than a
+    regular clone. Over most WAN connections (anything slower than
+    about 6 Mbps), uncompressed streaming is slower, because of the
+    extra data transfer overhead. This mode will also temporarily hold
+    the write lock while determining what data to transfer.
+    Default is True.
+
+``validate``
+    Whether to validate the completeness of pushed changesets by
+    checking that all new file revisions specified in manifests are
+    present. Default is False.
+
+``subpaths``
+""""""""""""
+Defines subrepositories source locations rewriting rules of the form::
+
+    <pattern> = <replacement>
+
+Where ``pattern`` is a regular expression matching the source and
+``replacement`` is the replacement string used to rewrite it. Groups
+can be matched in ``pattern`` and referenced in ``replacements``. For
+instance::
+
+    http://server/(.*)-hg/ = http://hg.server/\1/
+
+rewrites ``http://server/foo-hg/`` into ``http://hg.server/foo/``.
+
+All patterns are applied in definition order.
+
+``trusted``
+"""""""""""
+
+Mercurial will not use the settings in the
+``.hg/hgrc`` file from a repository if it doesn't belong to a trusted
+user or to a trusted group, as various hgrc features allow arbitrary
+commands to be run. This issue is often encountered when configuring
+hooks or extensions for shared repositories or servers. However,
+the web interface will use some safe settings from the ``[web]``
+section.
+
+This section specifies what users and groups are trusted. The
+current user is always trusted. To trust everybody, list a user or a
+group with name ``*``. These settings must be placed in an
+*already-trusted file* to take effect, such as ``$HOME/.hgrc`` of the
+user or service running Mercurial.
+
+``users``
+  Comma-separated list of trusted users.
+``groups``
+  Comma-separated list of trusted groups.
+
+
+``ui``
+""""""
+
+User interface controls.
+
+``archivemeta``
+    Whether to include the .hg_archival.txt file containing meta data
+    (hashes for the repository base and for tip) in archives created
+    by the :hg:`archive` command or downloaded via hgweb.
+    Default is True.
+``askusername``
+    Whether to prompt for a username when committing. If True, and
+    neither ``$HGUSER`` nor ``$EMAIL`` has been specified, then the user will
+    be prompted to enter a username. If no username is entered, the
+    default ``USER at HOST`` is used instead.
+    Default is False.
+``commitsubrepos``
+    Whether to commit modified subrepositories when committing the
+    parent repository. If False and one subrepository has uncommitted
+    changes, abort the commit.
+    Default is True.
+``debug``
+    Print debugging information. True or False. Default is False.
+``editor``
+    The editor to use during a commit. Default is ``$EDITOR`` or ``vi``.
+``fallbackencoding``
+    Encoding to try if it's not possible to decode the changelog using
+    UTF-8. Default is ISO-8859-1.
+``ignore``
+    A file to read per-user ignore patterns from. This file should be
+    in the same format as a repository-wide .hgignore file. This
+    option supports hook syntax, so if you want to specify multiple
+    ignore files, you can do so by setting something like
+    ``ignore.other = ~/.hgignore2``. For details of the ignore file
+    format, see the |hgignore(5)|_ man page.
+``interactive``
+    Allow to prompt the user. True or False. Default is True.
+``logtemplate``
+    Template string for commands that print changesets.
+``merge``
+    The conflict resolution program to use during a manual merge.
+    For more information on merge tools see :hg:`help merge-tools`.
+    For configuring merge tools see the merge-tools_ section.
+``patch``
+    command to use to apply patches. Look for ``gpatch`` or ``patch`` in
+    PATH if unset.
+``quiet``
+    Reduce the amount of output printed. True or False. Default is False.
+``remotecmd``
+    remote command to use for clone/push/pull operations. Default is ``hg``.
+``report_untrusted``
+    Warn if a ``.hg/hgrc`` file is ignored due to not being owned by a
+    trusted user or group. True or False. Default is True.
+``slash``
+    Display paths using a slash (``/``) as the path separator. This
+    only makes a difference on systems where the default path
+    separator is not the slash character (e.g. Windows uses the
+    backslash character (``\``)).
+    Default is False.
+``ssh``
+    command to use for SSH connections. Default is ``ssh``.
+``strict``
+    Require exact command names, instead of allowing unambiguous
+    abbreviations. True or False. Default is False.
+``style``
+    Name of style to use for command output.
+``timeout``
+    The timeout used when a lock is held (in seconds), a negative value
+    means no timeout. Default is 600.
+``traceback``
+    Mercurial always prints a traceback when an unknown exception
+    occurs. Setting this to True will make Mercurial print a traceback
+    on all exceptions, even those recognized by Mercurial (such as
+    IOError or MemoryError). Default is False.
+``username``
+    The committer of a changeset created when running "commit".
+    Typically a person's name and email address, e.g. ``Fred Widget
+    <fred at example.com>``. Default is ``$EMAIL`` or ``username at hostname``. If
+    the username in hgrc is empty, it has to be specified manually or
+    in a different hgrc file (e.g. ``$HOME/.hgrc``, if the admin set
+    ``username =``  in the system hgrc). Environment variables in the
+    username are expanded.
+``verbose``
+    Increase the amount of output printed. True or False. Default is False.
+
+
+``web``
+"""""""
+
+Web interface configuration. The settings in this section apply to
+both the builtin webserver (started by :hg:`serve`) and the script you
+run through a webserver (``hgweb.cgi`` and the derivatives for FastCGI
+and WSGI).
+
+The Mercurial webserver does no authentication (it does not prompt for
+usernames and passwords to validate *who* users are), but it does do
+authorization (it grants or denies access for *authenticated users*
+based on settings in this section). You must either configure your
+webserver to do authentication for you, or disable the authorization
+checks.
+
+For a quick setup in a trusted environment, e.g., a private LAN, where
+you want it to accept pushes from anybody, you can use the following
+command line::
+
+    $ hg --config web.allow_push=* --config web.push_ssl=False serve
+
+Note that this will allow anybody to push anything to the server and
+that this should not be used for public servers.
+
+The full set of options is:
+
+``accesslog``
+    Where to output the access log. Default is stdout.
+``address``
+    Interface address to bind to. Default is all.
+``allow_archive``
+    List of archive format (bz2, gz, zip) allowed for downloading.
+    Default is empty.
+``allowbz2``
+    (DEPRECATED) Whether to allow .tar.bz2 downloading of repository
+    revisions.
+    Default is False.
+``allowgz``
+    (DEPRECATED) Whether to allow .tar.gz downloading of repository
+    revisions.
+    Default is False.
+``allowpull``
+    Whether to allow pulling from the repository. Default is True.
+``allow_push``
+    Whether to allow pushing to the repository. If empty or not set,
+    push is not allowed. If the special value ``*``, any remote user can
+    push, including unauthenticated users. Otherwise, the remote user
+    must have been authenticated, and the authenticated user name must
+    be present in this list. The contents of the allow_push list are
+    examined after the deny_push list.
+``allow_read``
+    If the user has not already been denied repository access due to
+    the contents of deny_read, this list determines whether to grant
+    repository access to the user. If this list is not empty, and the
+    user is unauthenticated or not present in the list, then access is
+    denied for the user. If the list is empty or not set, then access
+    is permitted to all users by default. Setting allow_read to the
+    special value ``*`` is equivalent to it not being set (i.e. access
+    is permitted to all users). The contents of the allow_read list are
+    examined after the deny_read list.
+``allowzip``
+    (DEPRECATED) Whether to allow .zip downloading of repository
+    revisions. Default is False. This feature creates temporary files.
+``baseurl``
+    Base URL to use when publishing URLs in other locations, so
+    third-party tools like email notification hooks can construct
+    URLs. Example: ``http://hgserver/repos/``.
+``cacerts``
+    Path to file containing a list of PEM encoded certificate
+    authority certificates. Environment variables and ``~user``
+    constructs are expanded in the filename. If specified on the
+    client, then it will verify the identity of remote HTTPS servers
+    with these certificates. The form must be as follows::
+
+        -----BEGIN CERTIFICATE-----
+        ... (certificate in base64 PEM encoding) ...
+        -----END CERTIFICATE-----
+        -----BEGIN CERTIFICATE-----
+        ... (certificate in base64 PEM encoding) ...
+        -----END CERTIFICATE-----
+
+    This feature is only supported when using Python 2.6 or later. If you wish
+    to use it with earlier versions of Python, install the backported
+    version of the ssl library that is available from
+    ``http://pypi.python.org``.
+
+    You can use OpenSSL's CA certificate file if your platform has one.
+    On most Linux systems this will be ``/etc/ssl/certs/ca-certificates.crt``.
+    Otherwise you will have to generate this file manually.
+
+    To disable SSL verification temporarily, specify ``--insecure`` from
+    command line.
+``contact``
+    Name or email address of the person in charge of the repository.
+    Defaults to ui.username or ``$EMAIL`` or "unknown" if unset or empty.
+``deny_push``
+    Whether to deny pushing to the repository. If empty or not set,
+    push is not denied. If the special value ``*``, all remote users are
+    denied push. Otherwise, unauthenticated users are all denied, and
+    any authenticated user name present in this list is also denied. The
+    contents of the deny_push list are examined before the allow_push list.
+``deny_read``
+    Whether to deny reading/viewing of the repository. If this list is
+    not empty, unauthenticated users are all denied, and any
+    authenticated user name present in this list is also denied access to
+    the repository. If set to the special value ``*``, all remote users
+    are denied access (rarely needed ;). If deny_read is empty or not set,
+    the determination of repository access depends on the presence and
+    content of the allow_read list (see description). If both
+    deny_read and allow_read are empty or not set, then access is
+    permitted to all users by default. If the repository is being
+    served via hgwebdir, denied users will not be able to see it in
+    the list of repositories. The contents of the deny_read list have
+    priority over (are examined before) the contents of the allow_read
+    list.
+``descend``
+    hgwebdir indexes will not descend into subdirectories. Only repositories
+    directly in the current path will be shown (other repositories are still
+    available from the index corresponding to their containing path).
+``description``
+    Textual description of the repository's purpose or contents.
+    Default is "unknown".
+``encoding``
+    Character encoding name. Default is the current locale charset.
+    Example: "UTF-8"
+``errorlog``
+    Where to output the error log. Default is stderr.
+``hidden``
+    Whether to hide the repository in the hgwebdir index.
+    Default is False.
+``ipv6``
+    Whether to use IPv6. Default is False.
+``name``
+    Repository name to use in the web interface. Default is current
+    working directory.
+``maxchanges``
+    Maximum number of changes to list on the changelog. Default is 10.
+``maxfiles``
+    Maximum number of files to list per changeset. Default is 10.
+``port``
+    Port to listen on. Default is 8000.
+``prefix``
+    Prefix path to serve from. Default is '' (server root).
+``push_ssl``
+    Whether to require that inbound pushes be transported over SSL to
+    prevent password sniffing. Default is True.
+``staticurl``
+    Base URL to use for static files. If unset, static files (e.g. the
+    hgicon.png favicon) will be served by the CGI script itself. Use
+    this setting to serve them directly with the HTTP server.
+    Example: ``http://hgserver/static/``.
+``stripes``
+    How many lines a "zebra stripe" should span in multiline output.
+    Default is 1; set to 0 to disable.
+``style``
+    Which template map style to use.
+``templates``
+    Where to find the HTML templates. Default is install path.
