 # Josh's SVN wrapper script
 #
-# This wrapper script to Subversion supplements normal svn behavior by
-# adding additional functionality or modifying the output of the default
-# svn subcommands. Much of the functionality implemented here was inspired
-# by the way that git works.
-#
-# It is recommended to put this script in your $PATH as 'jsvn' or something
-# other than 'svn' and to make an alias svn='jsvn'.
-# For example, this .bash_aliases stanza will check if 'jsvn' is in your
-# path and automatically alias 'svn' to it if so:
-#   if [[ "$(which jsvn 2>/dev/null)" != "" ]]; then
-#       alias svn='jsvn'
-#   fi
-#
-# Implemented subcommands:
-#  add <file>...
-#   - add files as usual; add recursive contents of directories
-#  bisect <operation>
-#   operations:
-#    - init  initialize a new bisect operation
-#    - bad   mark the current revision as bad - containing the change sought
-#    - good  mark the current revision as good - older than the change sought
-#    - reset terminate the bisect operation and return to the original revision
-#  branch[es] [[-d] <branch_name>]
-#   - with no arguments, list branches with '*' by the current one
-#   - with -d, delete <branch>
-#   - otherwise, create a new branch from the current one
-#  tag[s] [[-d] <tag_name>] | [-m <old_tag_name> <new_tag_name>]
-#   - with no arguments, list tags
-#   - with -d, delete <tag>
-#   - with -m, rename <old_tag_name> to <new_tag_name>
-#   - otherwise, create a new tag from the current branch
-#  switch <short_name>
-#   - switch to 'trunk', branch name, or tag name without having to specify
-#     the full URL
-#   - falls back to Subversion "switch" if <short_name> doesn't exist
-#  merge <branch>
-#   - merge branch <branch> into the current WC path
-#   - falls back to Subversion "merge" if <branch> doesn't exist
-#  root
-#   - output root URL (for use on shell such as "svn log $(svn root)/tags")
-#  url
-#   - output repository URL of current working directory
-#  watch-lock
-#   - block until the lock on a file/URL is released
-#  users
-#   - show a list of contributing users to a SVN path
-#  binaries [--set-lock]
-#   - show a list of versioned binary files under the current path, with
-#     a prepended '*' for those with svn:needs-lock set
-#   - with --set-lock, set svn:needs-lock to '*' for binaries
-#  lockable [--remove] | [--status] <file[s]>
-#   - with no switches, set svn:needs-lock to '*' for file[s]
-#   - with --remove, remove svn:needs-lock' for file[s]
-#   - with --status, prepended '*' for those with svn:needs-lock set
-#  externals
-#   - print a list of the externals in the repository
-#  stash [command]
-#   - allow temporarily saving changes to the working copy without committing
-#   - the stashes behaves as a "stack" where "save" pushes a new stash object
-#     and "pop" pops the newest one from the top of the stack
-#   commands:
-#     save (default if not specified):
-#      - save changes as a "stash" object and revert them from working copy
-#      - this currently only works with changes to already-versioned files
-#     list:
-#      - show a list of all stash objects
-#     pop [id]:
-#      - apply the stash object <id> back to the working copy
-#      - the stash object is removed if it was successfully applied
-#      - <id> defaults to the newest stash object created
-#     show [id]:
-#      - display the diff stored in stash with ID <id>
-#      - <id> defaults to the newest stash object created
-#     drop [id]:
-#      - delete stash object <id>
-#      - <id> defaults to the newest stash object created
-#
-# The following subcommands are executed using their native handler, but
-# have their output simplified and/or colorized:
-#  - diff
-#  - log
-#  - status
-#  - update
-#
-# If the subcommand name begins with two leading underscores ("__"), the
-# underscores will be stripped and the command will be handled by native
-# Subversion without any jsvn processing.
-#
-# Configuration:
-#
-# jsvn will execute the file ~/.jsvn, if it exists, as a Python script.
-# Variables written to will be used as configuration directives.
-# Available configuration directives:
-#   use_color: True or False to enable/disable colorization of svn output
-#   use_pager: True or False to enable/disable automatic piping of svn
-#              output to a pager program
-#   pager:     A string specifying the pager program (and args) to execute
-#   aliases['XXX']: A string or list defining the alias 'XXX'. A string
-#              can be used if the alias expands to a single argument. A
-#              list must be used to pass multiple arguments to svn.
-#
-# Configuration Examples:
-#   pager = 'less -FRXi' # enable case-insensitive searching in less
-#   aliases['revert'] = ['revert', '-R'] # default to recursive reverts
-#   aliases['s'] = ['status', '--ignore-externals']
-#   aliases['status'] = '__status' # ignore jsvn processing of status command
