+ * src/net/messagin.cpp, src/net/messageout.cpp, src/net/network.cpp:
+ removed replaced MACOSX defines with big endian defines
+ * src/graphics.cpp, src/graphics.h: added screenshot method
+ * src/game.cpp: added code, so that when one presses 'alt-p' (for
+ picture), it takes a screenshot and saves it to a png
+ * src/Makefile.am, config.ac: added png library stuff
+
2005-09-17 Matthias Hartmann <hartmann.matthias@gmail.com>
* src/engine.cpp: [TARGET] text over player
