# Installs a relatively minimalist version of the GPAC tools. The
# most commonly used tool in this package is the MP4Box metadata
# interleaver, which has relatively few dependencies.
#
# The challenge with building everything is that Gpac depends on
# a much older version of FFMpeg and WxWidgets than the version
# that Brew installs
