I’m using JSMin to compress my Javascripts on the fly - [http://code.google.com/p/jsmin-php/](http://code.google.com/p/jsmin-php/).

Unfortunately, it seems to break any jQuery source I have - whether it be pre-minified, packed, or neither.

Firebug says “$ is not defined” - so obviously any time that I use jQuery, I get errors.

Any reason why?

Thanksies
