# To add a new Python here:
# 1. Patch src/libs/xpcom18a4/python/Makefile.kmk (copy the previous impl's logic)
#    Do NOT skip this part. It'll end up silently not-building the Python extension
#    or otherwise misbehaving if you do.
#
# 2. Then update PYTHON_COMPAT & set PYTHON_SINGLE_TARGET for testing w/ USE=python.
#
#  May need to look at other distros (e.g. Arch Linux) to find patches for newer
#  Python versions as upstream tends to lag. Upstream may have patches on their
#  trunk branch but not release branch.
#
#  See bug #785835, bug #856121.
