#!/bin/bash
#
# Generic wrapper for bash functions so they can be invoked by external tools.
# If the wrapper filename (or symlink) ends in 'w' then this is stripped and
# the function is invoked with the --wait option before any command line ones.
#
# The function definition must be in a file in /etc/profile.d/ of the form
# *.CMD.sh when CMD is the symlink filename without any trailing 'w' character.
