# Host-side tools for the JoeyLib asset pipeline.
#
# These build with the host's default `cc` (no cross-toolchain) into
# build/tools/. Currently:
#   joeyasset   -- PPM (P6) -> .jas converter
#   modloopend  -- inject an E8FF stop-marker pattern into a .MOD so
#                  the Amiga audio HAL can honor PlayMod(loop=false).
#                  joeymod invokes this transparently for Amiga output.
