#
# git-flow-completion
# ===================
#
# Bash 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 branch names (for `git-flow feature track`)
#
#
# Installation
# ------------
#
# To achieve git-flow completion nirvana:
#
#  0. Install git-completion.
#
#  1. Install this file. Either:
#
#     a. Place it in a `bash-completion.d` folder:
#
#        * /etc/bash-completion.d
#        * /usr/local/etc/bash-completion.d
#        * ~/bash-completion.d
#
#     b. Or, copy it somewhere (e.g. ~/.git-flow-completion.sh) and put the following line in
#        your .bashrc:
#
#            source ~/.git-flow-completion.sh
#
#  2. If you are using Git < 1.7.1: Edit git-completion.sh and add the following line to the giant
#     $command case in _git:
#
#         flow)        _git_flow ;;
#
