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