cmd line parsing emulating sv[kn]

[Paul Makepeace]

I have a script where I'd like to emulate svn's -r option. It goes like,
  -r 1676
  -r1676 (i.e. whitespace not significant)
  -r168:200 (I can probably manage to parse out the two numbers...)

I've used Getopt::Long (since I know it) with GetOptions("r=s" => \$revs)
but Go::L seems to require a space between switch & arg which is confusing
for anyone using sv[kn].

Any suggestions which module to use?

Is there a Giant List of CPAN CLI Parsers and Their Features anywhere?
