In early 2002, Priority Health had a problem to solve that required sophisticated dependency chaining and scheduling. I was asked to help by writing a script to run the process. It ended up being a generic solution that got picked up by other groups within Priority Health. In August of 2006, I was given permission to open source the project for the Pittsburgh Perl Workshop.
Here are my slides from the presentation I gave at PPW:
PAGE-PPW2006-SLIDES.odp
PAGE-PPW2006-SLIDES.pdf some pdf readers don't like this
Here's the README for PAGE "Rel0". Rel0 is the minimally modified release of the code from Priority Health. The two biggest changes were adding Log::Log4perl support and a cleaner configuration mechanism, PAGE::Config. It can be downloaded here: PAGE-Rel0-0.tar.gz.
There is more that I've written under the perl section that will eventually end up on this page.
