+Currently the graphics is stored in the PNG file format (other formats
+may be readible by some clients).
 
-If you alter the graphics, then notice that after saving the new xpm
-file, you must manually mark the first color as transparent. Look at
-the original xpm-files, to see how this is done. Failing to do this
-results in crash(the mask-pixmaps will not be generated).
+If you alter the graphics, then make sure that the background remains
+transparent.  Failing to do this means the mask-pixmaps will not be
+generated properly, which will certainly not give any good results.
 
 Each terrain tile is drawn in 16 versions, all the combinations with
 with a green border in one of the main directions. Hills, mountains,
 forests and rivers are treated in special cases.
 
-[IMO we should have gotten rid of libxpm long ago. The graphics should
-be drawn in 24bit, and then quantized runtime, if the client is displayed
-on a pseudocolor display. 
-The current tile system should be converted to something like civ2's.
+The XAW client requires that the graphics be stored in "paletted" PNGs,
+which for graphics with few colors is probably a good idea anyway. It also
+has a limited number of colors available, although it will try to match
+similar-looking colors after the existing supply has been exhausted.  Of
+course, not every tileset has to be usable by the XAW client.

 They get away with drawing way less tiles, and it looks better. -PU]
