+"""Windows ICO file crusher.
+
+Optimizes the PNG images within a Windows ICO icon file. This extracts all of
+the sub-images within the file, runs any PNG-formatted images through
+optimize-png-files.sh, then packs them back into an ICO file.
+
+NOTE: ICO files can contain both raw uncompressed BMP files and PNG files. This
+script does not touch the BMP files, which means if you have a huge uncompressed
+image, it will not get smaller. 256x256 icons should be PNG-formatted first.
+(Smaller icons should be BMPs for compatibility with Windows XP.)
