Plugin dependencies

Hi everyone!

I'm writing my first ever Rails plugin, and I'm trying to figure out
what the best way (in 2.3) to manage plugin dependencies is. Google
doesn't seem to yield much that is applicable to my current situation,
and the Rails docs themselves are quite weak in this area (or I'm
looking at the wrong class).

basically there is very little support for dependencies, core's
position on this is 'if you want dependencies, use gems' (plugins can
be loaded from gems). If the plugin you want to depend on isn't
available in gem form then it isn't hard to make that plugin also work
as a gem according to http://www.practicalecommerce.com/blogs/post/438-The-Blurring-Line-Between-Plugins-and-Gems
