Call for Help: need script for patching ports tree, building with poudriere

I wrote myself a similar script, but it is very basic (and PHP).

It:
- assumes that patches are generated against /usr/ports (which makes 
applying much easier)
- apply the patches
- get the ports affected by the diff with svn diff
- runs portlint
- runs poudriere for many versions...
- reset every change made to the portstree

There are many glitches and it is not this fast, but it safe much time 
while i wrote port updates. I get a very simple report if everything is 
fine and then i submit my PR. But of course any other workflow is possible.

I aimed to support multiple poudriere server to speed up the process. 
But i have way more ideas than time... ;)

I will help you, but currently (which means till the end of the year) i 
am very short on time.

Are there any requirements to the script in language, performance, etc. ?

Greetings,
