# Caution: there are two separate, independent build systems:
# 'makepanda', and 'ppremake'.  Use one or the other, do not attempt
# to use both.  This file is part of the 'makepanda' system.
#
# To install panda using this script, type 'installpanda.py'.
# To specify an alternate location than the filesystem root /,
# either pass it as only argument or set the DESTDIR environment
# variable. This script only functions on Linux, for now.
