Interesting - I use help2man wherever I can, but am open to suggestions for alternatives.

Please do tell if interested in the reasons why - but perfectly understandable if you don't really care for that. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ * Sponsorship: https://ko-fi.com/drjones [x] quote me freely [ ] ask before reusing [ ] keep private
