This post is not about perl plugins (what would that be?). But about programs that use plugins. One of those programs is Qpsmtpd, a perl mail server. They use a special and very nice way to use plugins.
Moveable Type is another perl program, that uses plugins. These plugins are a little bit simpler than the qpsmtpd plugins, but just as powerful.
And now there is another perl program that uses plugins, my webshop. It is really nice to see how easy it is to create a new type of shop on top of the current code. I can’t yet show it, but within a few days it will be online.
