# (*) pyglet developers put random utilities in `tools`, without much
# regard to licenses. The development tree at 2012-10-19 included some GPL,
# for example. Given the project's culture, non-free code could be included
# in the future, so it's better to remove the directory to be on the safe side.

# (**) pyglet uses the patented S3 texture compression algorithm to
# encode/decode DirectX texture files (*.dds).
# Removing the two files disables the feature cleanly (see the guarded
# dss import in pyglet/image/codecs/__init__.py).
