# chpl parameter completion

# Tab autocompletion for chpl options and directories/.chpl files in bash
# Source this file to enable this autocompletion.  To automatically enable
# autocompletion, source this file from your .bashrc file.

# This file was generated with the script:
# $CHPL_HOME/util/devel/gen-chpl-bash-completion

# This is modeled after the example at:
# http://tldp.org/LDP/abs/html/tabexpansion.html
# and Dennis's answer to this question:
# https://superuser.com/questions/564716/bash-completion-for-filename-patterns-or-directories
