sub - Alex's wrapper for subversion

Version: #{Sub::VERSION::STRING}

Usage:
sub co project_name [dir_name]
  checks out [base_url]/project_name/trunk into ./project_name (or dir_name if specified)
sub up [dir]*
  fast update (default command, so 'sub dir...' or just 'sub' work too)
sub help
  prints this message

Options:
--verbose, -v
    lots of output
--quiet, -q
    no output at all except for errors
--help, -h
    prints this message
--clean, -c
    'up' command removes all unversioned files and directories
--url [base_url]
    sets base repository url for 'co' command
    (default is ENV['SUB_BASE_URL'] or ENV['SVN'] or #{DEFAULT_BASE_URL})
--version
    prints release version
