This directory is for optional patches. Any *.diff files found here will be applied to the sic source in ASCIIbetical order, when the SlackBuild is run. If the order of patches matters (if later ones depend on earlier ones), name them e.g. 001-foo.diff, 002-bar.diff, etc. Upstream provides a few patches here: http://tools.suckless.org/sic/patches/
