Re: Fw: [Dynapi-Dev] compressing files

Interesting idea, but I'm trying to keep the <script> tags in the
browser to a minumum. I finished off the code the way I suggested this
morning and it seems to work well, so I'll probably just stick with it
that way. This way also allows me to just include "myfile.js" in my
page and get everything I need.
