@@ -0,0 +1,6 @@
+pngcrush reads in a PNG image, and writes it out again, with the
+optimum filter_type and zlib_level. It uses brute force (trying
+filter_type none, and libpng adaptive filtering, with compression
+levels 3 and 9).  It does the most time-consuming method last in case
+it turns out to be the best. Optionally, it can remove unwanted
+chunks or add gAMA and sRGB chunks.
