How can you make a patch ?

* Put the original AfterStep in some dir, let's say AfterStep-old/

* Put your new source tree in something like AfterStep-new/

* Then run :
diff -N -u -r AfterStep-old/ AfterStep-new/ > yourname-patch
gzip yourname-patch

* People will apply your patch by just running :
tar -zxvf AfterStep-old.tgz
gunzip yourname-patch.gz
patch -p0 < yourname-patch
