# SYNTAX:
# build_perl_modules -d dest_dir [-c] [-m] [-t] [-i] [-s <section>] tarball_dir
#
# DESCRIPTION:
# Installs perl modules found in tarball_dir
# Expects a file called install_order, containing one line per distribution name
# Will take action against each distribution in turn
# -d is a necessary destination directory for the perl mods
# If -c is set, will remove the module build directories and exit
# If -e is set, will extract module
# If -m is set, will run perl Makefile.PL and make
# If -t is set, will run make test
# If -i is set, will run make install
# If -s <section> specified will only work on that section in the
# install_order file - defaults to first section only
# Options are discrete. This is because an overall ./configure, make, make test, make install
# are run in different invocations. Obviously, you can't run a -t without a -m, but there's no
# checking here for that
# Can only use base modules
