# This repo doesn't use tags for releases, therefore we checkout specific commits.
# The date is the commit's date.
# Also, they're using a very complex build system. For this reason we run their Makefile
# which creates its own Python virtual environment
#
# Requires a few packages in order to compile:
# - texlive-full
# - curl
