+# DOOM (doomgeneric) for MontaukOS
+#
+# Upstream: https://github.com/ozkl/doomgeneric (submodule at upstream/,
+# pinned; no local patches). MontaukOS support lives entirely in src/:
+# doomgeneric_montauk.c (video/input), i_sound_montauk.c (audio),
+# doom_wad_check.cpp (missing-WAD dialog).
+#
+# doom1.wad is proprietary id Software content and is deliberately NOT
+# bundled; the engine (GPLv2) ships without it.
