   7# You need git's bash completion script installed somewhere, by default it
   8# would be the location bash-completion uses.
   9#
  10# If your script is somewhere else, you can configure it on your ~/.zshrc:
  11#
  12#  zstyle ':completion:*:*:git:*' script ~/.git-completion.sh
  13#
  14# The recommended way to install this script is to copy to '~/.zsh/_git', and
  15# then add the following to your ~/.zshrc file:
  16#
  17#  fpath=(~/.zsh $fpath)
