git-stats --help
A GitHub-like contributions calendar, but locally, with all your git commits.

usage: git-stats [start] [end] [options] [data]

start:                    Optional start date
end:                      Optional end date

options:
  -v                      Displays version information.
  -h --help               Displays this help.
  --no-ansi               Doesn't use ANSI colors in the squares.
  --record <data>         Records a new commit. Don't use this unless you are
                          a mad scientist. If you are a developer, just use this
                          option as part of the module.
  --light                 Enable the light theme.

examples:
   git-stats # Displays your commit calendar
   git-stats -v
   git-stats -h
   git-stats --light # Light mode
   git-stats '1 January 2012' # All the commits from 1 January 2012, to now
   git-stats '1 January 2012' '31 December 2012' # All the commits from 2012

Your commit history is kept in the .git-stats, in your $HOME directory (~/)
