+PS2 test renderer
+=================
+
+This is a basic RW renderer for PS2.
+There is a bunch of unrelated code since I adapted an earlier program of mine.
+
+To compile you need the ps2toolchain and ee-dvp-as from the Sony SDK
+(dvp-as from the ps2toolchain segfaults when encountering MPG,
+this should be fixed).
+
+So far the program can render PS2 native geometry
+in the default or skin format (no PDS pipes as used in San Andreas supported yet).
+The files are read from host: (see main.cpp)
+so you can use e.g. ps2link on a real PS2 or pcsx2 with the host device enabled.
