Symaptic: Branches

Environment Variables
 HG
 Path to the 'hg' executable, automatically passed when running hooks,
 extensions or external tools. If unset or empty, this is the hg
 executable's name if it's frozen, or an executable named 'hg' (with
 %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is
 searched.
 HGEDITOR
 This is the name of the editor to run when committing. See EDITOR.
 (deprecated, use configuration file)
 HGENCODING
 This overrides the default locale setting detected by Mercurial. This
 setting is used to convert data including usernames, changeset
 descriptions, tag names, and branches. This setting can be overridden
 with the --encoding command-line option.
 HGENCODINGMODE
 This sets Mercurial's behavior for handling unknown characters while
 transcoding user input. The default is "strict", which causes
 Mercurial to abort if it can't map a character. Other settings include
 "replace", which replaces unknown characters, and "ignore", which
 drops them. This setting can be overridden with the --encodingmode
 command-line option.
 HGENCODINGAMBIGUOUS
 This sets Mercurial's behavior for handling characters with
 "ambiguous" widths like accented Latin characters with East Asian
 fonts. By default, Mercurial assumes ambiguous characters are narrow,
 set this variable to "wide" if such characters cause formatting
 problems.
 HGMERGE
 An executable to use for resolving merge conflicts. The program will
 be executed with three arguments: local file, remote file, ancestor
 file.
 (deprecated, use configuration file)
 HGRCPATH
 A list of files or directories to search for configuration files. Item
 separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set,
 platform default search path is used. If empty, only the .hg/hgrc from
 the current repository is read.
 For each element in HGRCPATH:
 - if it's a directory, all files ending with .rc are added
 - otherwise, the file itself will be added
 HGPLAIN
 When set, this disables any configuration settings that might change
 Mercurial's default output. This includes encoding, defaults, verbose
 mode, debug mode, quiet mode, tracebacks, and localization. This can
 be useful when scripting against Mercurial in the face of existing
 user configuration.
 Equivalent options set via command line flags or environment variables
 are not overridden.
 HGPLAINEXCEPT
 This is a comma-separated list of features to preserve when HGPLAIN is
 enabled. Currently the only value supported is "i18n", which preserves
 internationalization in plain mode.
 Setting HGPLAINEXCEPT to anything (even an empty string) will enable
 plain mode.
 HGUSER
 This is the string used as the author of a commit. If not set,
 available values will be considered in this order:
 - HGUSER (deprecated)
 - configuration files from the HGRCPATH
 - EMAIL
 - interactive prompt
 - LOGNAME (with "@hostname" appended)
 (deprecated, use configuration file)
 EMAIL
 May be used as the author of a commit; see HGUSER.
 LOGNAME
 May be used as the author of a commit; see HGUSER.
 VISUAL
 This is the name of the editor to use when committing. See EDITOR.
 EDITOR
 Sometimes Mercurial needs to open a text file in an editor for a user
 to modify, for example when writing commit messages. The editor it
 uses is determined by looking at the environment variables HGEDITOR,
 VISUAL and EDITOR, in that order. The first non-empty one is chosen.
 If all of them are empty, the editor defaults to 'vi'.
 PYTHONPATH
 This is used by Python to find imported modules and may need to be set
 appropriately if this Mercurial is not installed system-wide.
