This task is to complete HaikuPorts trac ticket #301:
That is to create the Source: entry in the .OptionalPackageDescription file. For this IF the user tries to build the app with the -d option AND (the license is a GPL or LGPL license) OR (the -z option is selected) THEN haikuporter should also build the patched source zip file and add the url to the .OptionalPackageDescription file that gets including into the binary zip package.
