I can barely imagine an integer large enough to represent the number of
times I prefer to develop that code in ST rather in Apache's configuration
files, rewrite rules and those friends. So.. after almost all day
configuring some rules for some apps I disagree with being that a desirable
thing to have, simultaneously I agree that would be wonderfully time saving
for seasiders not even have to write it in first place.

If you 1) freely develop your app asimilating anytime by evaluating 

	XXLibrary refreshResources

(that if you have the files under imagePath/XXLibrary) to develop with
guaranteed fresh versions of files, until you 2) want to deploy and let the
image to tell you wich files in which dir structure the app will expect by
	(WADispatcher default entryPointAt: 'applicationName') deployFiles
and 3) you copy the tree found at imagePath/files to the proper location,
then you only need some tuned rewrite rules to make apache preceed the
seaside image to serve them (in exactly the same version but slower).

I make this to be less error prone at deployment. Comparisions become
irrelevant syncrhonization instantaneously archieved (if files correctly

I wanted to add that the /seaside/ issue adds no value to any project but
seaside itself. And sadly is kind of pain to take it out. We love/need
seaside so we most probably put a "powered by seaside" or some other
branding stuff like that (beside support/bugfixes/etc) which IMHO has a lot
more sense than a piece of anti-minimalistic URL.
