[Mapbender-dev] Packer (code conventions)

[Christoph Baudson (WhereGroup)]

Hi Paul, hi list,

thanks for the hint, Paul; Indeed, jsmin is an alternative worth 
considering.

Take a look at this description

http://www.crockford.com/javascript/jsmin.html

The compression rates are not as high as with Dean Edwards' packer, but 
the code remains (to some degree) human-readable. And the semicolon 
after function definitions would not be mandatory.

Any opinions?

Christoph
