[Mapbender-dev] Packer (code conventions)

[Paul Spencer]

There is also jslint from Douglas Crockford ... it doesn't compress/ 
minify but it does check your code for syntactic cleanness, which  
helps the compressors do the right thing.

I am slowly running this on my code with some embarrassing  
results :)  On the other hand, I've been able to pack my individual  
js files together and compress them reasonably well since I delinted  
them

Cheers

Paul
