       If you like GNU Parallel:

       · Give a demo at your local user group/team/colleagues

       · Post the intro videos and the tutorial on Reddit, Diaspora*,
forums, blogs, Identi.ca, Google+, Twitter,
         Facebook, Linkedin, mailing lists

       · Request or write a review for your favourite blog or magazine

       · Invite me for your next conference

       If you use GNU Parallel for research:

       · Please cite GNU Parallel in you publications (use --bibtex)

       If GNU Parallel saves you money:

       · (Have your company) donate to FSF or become a member

None. Only when you want to use positional replacement strings does it
make a difference.

Because no one have submitted a good patch to fix it.
