# git-flow-completion
# ===================
#
# Fish completion support for [git-flow](http://github.com/nvie/gitflow)
#
# The contained completion routines provide support for completing:
#
#  * git-flow init and version
#  * feature, hotfix and release branches
#  * remote feature, hotfix and release branch names
#
#
# Installation
# ------------
#
# To achieve git-flow completion nirvana:
#
#  1. Install this file in your `~/.config/fish/completions` folder.
