Quick Update: this apparently only works with Zend Studio for Eclipse. Sorry for any confusion if you’re trying to figure out where the f$#@ those dialogs are.
All of my projects reside in an SVN repository and now they’re starting to get accessed by multiple users. Typically with eclipse, I would just have a project that contained externally required libraries – such as the Zend Framework – but now the location of this is required to be more flexible.
