This is quite an easy process, because suck's sucknewsrc files can be used as newsstar newsrc files without alteration, just by moving/renaming them. Converting suck active-ignore files to newsstar ignore files requires some more work, but very little. The main things to watch out for are that in perl regexps, . (period) means match any character, so if you want to exactly match a . in a group name, you should precede it with a backslash. Also, * means match any number of the preceding character, so * in active-ignore should be replaced with .*. There is no need to use trailing or leading .*s because patterns match any part of a group name.
