[OpenLayers-Dev] Dynamic Build Technique -- from script.aculo.us

[Cameron Shorter]

We dynamic loading in Mapbuilder.
However, we have plans to drop this functionality.

The downsides of dynamic loading are:
* The user needs to download multiple JS files instead of one. This is 
slower.
* It is harder to compress JS if it is spread across multiple files.
The best compression is achieved when you reduce the size of variable 
names from "counter" to "x1" or similar. This only works if the 
compression program is assessing all the JS source at once. Ie, you 
can't run:
compress file1
compress file2
compress file3

You need to run
compress file1 file2 file3
