# gitissius-completion
# ===================
#
# Bash completion support for [gitissius](https://github.com/glogiotatidis/gitissius)
#
#
# Installation
# ------------
#
# To achieve gitissius 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. Copy it somewhere (e.g. ~/.gitissius-completion.bash) and put the following line in your .bashrc:
#
#         source ~/.gitissius-completion.bash
#
#   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:
#
#      issius) _git_issius ;;
