Rob Allen has a new post today about the upcoming Zend Framework 2 release and how, with a little convincing, you can get ZF1 and ZF2 to play nicely alongside each other with Zend_Tool.

If you want to play with the development versions of Zend Framework 2.0, then it's handy to be able to create ZF2 projects using the ZendTool command line tool. Rather unhelpfully, ZF2's ZendTool uses the same ini file (~/.zf.ini) as ZF1's Zend_Tool and the same zf.sh script filename, so you can't just put zf2 on to your path and it'll all just work. I am assuming that you're like me and have production sites using ZF1, so you probably don't want to mess up your current zf.sh usage. This is how I implemented side-by-side ZF cli scripts.

His is a three step process that involves the install of a copy of the Zend Framework 2 somewhere on your system, creating a new ini file for it and create a new bash script (called "zf2") that defines the new ini file location as a command line variable.
