+Image files are checked for permissions (0644), filename (extension
+must match filetype, e.g. a GIF image must not be named image.jpg),

+Patch files (anything named *.diff or *.patch) are checked for
+permissions (0644) and DOS/Windows CRLF line endings. If a patch
+file has CRLF endings, it B<cannot> be checked into SBo's repository,
+because git will strip the CR (\r) from every line, meaning the patch
+will fail to apply. In this case, the best solution is to gzip the
+patch, and have the SlackBuild use e.g. "zcat $CWD/blah.diff.gz |
+patch -p1" to apply it.
