# FIXME:
# * will we be able to add javascript support through emscripten library?
# This library seems to be highly unfriendly to be installed system wide!
# * add USD (Pixar's Universal Scene Description) support, see
# https://github.com/PixarAnimationStudios/USD
# * add support for Unity(3D) and Maya plugins?
# Notes:
# - We don't add USE flags for ccache and distcc, because the library builds
# in minimal time (a few seconds)
