Hi Greg,
after more than a year I resurerected pnm2ppa port for my home use 
yesterday. It was lot of work for me - I did some port many years ago 
and converting this old port to staging was not easy for me. I tried to 
build it with "poudrier testport" and it succeeded.

So what to do next to submit PR in right format?
Should I send diff against old port version, or full archive of new version?
