[PATCH] New "server" script

[Pier Fumagalli <pi...@betaversion.org>]

If you're trying out that idea of mine for having a cocoon "server"
distribution, I have a _much_ much nicer startup script... (if it's on the
mailing list, I ain't gonna loose it!) :-) Attached...

Also, any thought about my patch for having cocoon.xconf and logkit.xconf
outside of WEB-INF. Can I get that applied??? I'm tired of patching it up on
every machine where I do "cvs co" :-) :-) :-)

Have fun...
