/**
+ * \brief hg_backout command for hglib API.
+ *
+ * Prepare a new changeset with the effect of rev undone in the current
+ * working directory.
+ *
+ * If rev is the parent of the working directory, then this new changeset is
+ * committed automatically. Otherwise, hg needs to merge the changes and the
+ * merged result is left uncommitted.
+ *
+ * By default, the pending changeset will have one parent, maintaining a linear
+ * history. With --merge, the pending changeset will instead have two parents:
+ * the old parent of the working directory and a new child of REV that simply
+ * undoes REV.
+ *
+ * Options/Argument list option:
+ *
+ * --merge merge with old dirstate parent after backout
+ * --parent parent to choose when backing out merge
+ * (DEPRECATED)
+ * -r, --rev revision to backout
+ * -t, --tool specify merge tool
+ * -I, --include include names matching the given patterns
+ * -X, --exclude exclude names matching the given patterns
+ * -m, --message use text as commit message
+ * -l, --logfile read commit message from file
+ * -d, --date record the specified date as commit date
+ * -u, --user record the specified user as committer
+ *
+ * \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 prompt A function that will handle prompts messages.
+ * A NULL pointer will use an abort function.
+ * \param argument The option list. Will contain all option that you wish.
+ * \retval exitcode To indicate the end of backout_command.
+ *
+ * errno can be:
+ * - hg_rawcommand errors
+ * */
