Crusty curmudgeon here, still sticking to good old getopt. It may be
simple, crude even, but on the other hand it doesn’t try to do too
much. It may be “soft-deprecated”, but at least that means it will
keep on doing what it does for the foreseeable future.

It doesn’t offer built-in help, but then I also like to write man
pages (yes, proper documentation) for my more complex scripts.
