# You will have to install the git gem for this to work:
#   gem install git
#
# You will need to make the script executable
#   chmod +x post-commit
#
# Name this file 'post-commit' and drop it in the directory '.git/hooks'  in
# any repository that you want to log. Make sure the file is executable. You
# can also add this to your git templates, which will put it in every new
# repository or to existing repositories by re-running git init.  
# 
# A commit message in the log should look this this:
#   2013-07-26-11-25-55 [repository:branch] First line of commit message
