# Python USD AR — adds Apple's "Preliminary_" AR schemas on top of python-usd.
#
# These schemas (Preliminary_AnchoringAPI, Preliminary_Behavior, Preliminary_Trigger,
# Preliminary_Action, Preliminary_ReferenceImage, Preliminary_Text) come from Apple's
# USDZ Schemas for AR addendum and are still not upstreamed into OpenUSD, so they
# have to be code-generated and compiled into libusd at build time.
#
# See: https://developer.apple.com/documentation/arkit/usdz_schemas_for_ar
