| Subject: | Feature request: required_or, needs_or |
Thought it might be nice to add a couple features required_or and
needs_or.
Each will let the user define one and only one option from a set of
choices. A real world example may be that your program accepts a userid
or a username. One of but not both options are required to run
successfully.
If this is something you'd like to look at I've written the code, tests
and docs for the changes here: https://github.com/kmcgrath/getopt-
lucid/tree/needs_or
