# mpirun completion v1.1
#
# Bash completion script for Open MPI's mpirun
#
# Installation:
# If bash completion is not already installed, follow the instructions at:
# http://anonscm.debian.org/gitweb/?p=bash-completion/bash-completion.git;a=blob_plain;f=README
#
# Then install mpirun completion by dropping this file into either the system bash_completion.d
# (usually found in /etc) or somewhere in your home directory (~/.bash_completion.d is a good place).
# If installing the script in a location other than the system-wide location, you will probably need
# to add the following to either ~/.bash_profile or ~/.bash_completion:
#
# [ -r /path/to/mpirun.sh ] && . /path/to/mpirun.sh
# find available MCA variables
