+/**
+ * \brief hg_resolve command for hglib API.
+ *
+ * Merges with unresolved conflicts are often the result of non-interactive
+ * merging using the internal:merge configuration setting, or a command-line
+ * merge tool like diff3. The resolve command is used to manage the files
+ * involved in a merge, after hg merge has been run, and before hg commit is run
+ * (i.e. the working directory must have two parents). See hg help merge-tools
+ * for information on configuring merge tools.
+ *
+ * Options/Argument list option:
+ * 
+ *	-a, --all		select all unresolved files
+ *	-l, --list		list state of files needing merge
+ *	-m, --mark		mark files as resolved
+ *	-u, --unmark	mark files as unresolved
+ *	-n, --no-status	hide status prefix
+ *	-t, --tool		specify merge tool
+ *	-I, --include	include names matching the given patterns
+ *	-X, --exclude	exclude names matching the given patterns
+ *
+ * To get locate information use the returned hg_linestream_buffer strucutre 
+ * with hg_fetch_line_entry() function.
+ *
+ * \param handle The handle of the connection, wherewith I want to communicate
+ * \param callback A function that will handle error data. 
+ *                 A NULL pointer will ignore error data.
+ * \param argument The option list. Will contain all option that you wish.
+ * \retval hg_linestream_buffer A pointer to hg_linestream_buffer structure if 
+ *                              successful
+ * \retval NULL to indicate an error, with errno set appropriately.
+ 
+ * errno can be:
+ *      - hg_rawcommand errors
+ *
