HEY LOOK! THIS ISN'T QUITE DONE YET!! REALLY. THERE ARE STILL BUGS.
5+
6+
Start here: [http://www.aaronland.info/weblog/2010/12/06/urmum/#enplacify](http://www.aaronland.info/weblog/2010/12/06/urmum/#enplacify)

lib_emplacify is *designed* to be used in conjuction with [flamework](https://github.com/straup/flamework) (as of this writing, specifically my fork). Although it probably doesn't need to be part of core flamework I've already found uses for it in two other projects that [hold hands](https://github.com/Citytracking/dotspotting/blob/master/README.FLAMEWORK.md) with flamework so now it's a little bundle of libraries and functions and can check out and slot in where necessary.
9+
10+
If you don't want to bother using flamework though I've included just enough real and mock flamework code so that this code will run on its own. Take a look at the `test.php` file for details.
