If you're interested into using Travis-CI for your Perl projects, here's a few pointers that you should not miss:

• Graham Knop's article introducing the helpers;
• fREW's article on using it, although the specific setup refers to a previous repository that can still be cloned but it's probably not maintained any more (not reachable from Github's portal, anyway);
• Dave Cross's article with slides.

Too bad that it took me so long to find them out.
