#
# Completion for Environment Modules `module' alias.
#
# See http://sourceforge.net/projects/modules/
#     http://modules.sourceforge.net/
#
# There are several versions of modules that are commonly used.  Older
# Cray UNICOS systems and many other sites use 2.2.2b.  The latest GPL'd
# version is 3.1.6.  But the module alias is somewhat self-documenting
# via the `module help' command, so use that to print the options.
#
# Programmable completion might be more difficult under tcsh since the
# module command is an alias, and the `module avail' command returns
# its output as stderr.

# Test for existence of /etc/profile.d/modules.sh too because we may end up
# being sourced before it and thus before the `module' alias has been defined.
