# A metapackage is a file containing a list of packages.
# This script just installs all the packages in a metapackage.
# Remeber that mkjail template == metapkg metapackage.
# 

#
# TODO
#
# In the mean term, metapkg will not be developed, but the code will rest
# until someone need it. Some ideas to think for the future of metapkg would
# be a better integration with simplepkg structure, like:
#
# - By default metapkg searches by a slack-required in the package/slackbuilds repos
# - With -f, metapkg uses a local file (template, slack-required or tagfile)
