type FunOptDescr cfg = OptDescr (Either (IO ()) (cfg -> cfg)) Source #

Generate a main action that parses the given command line options (while always adding commonOptions).

commonOptions :: String -> String -> [FunOptDescr cfg] -> [FunOptDescr cfg] Source #

Common definitions for -v and -h, given the list of all other options.
