Does not work here. :-(
[Fri Jan 27 20:56:47 2006] [error] mod_ruby: error in ruby

This error is the same for gzipped and normal transfer. Looks like neither
Apache::Request nor ZLip::GZipWriter is subclassed from IO...?
For quick fix, you could use "puts ox.to_s" instead of
"ox.dump($stdout)" (which will be another step away from my progress bar ;)

Thats what the out.close in map.rb was for. And you could flush the stream, if
it is not a gzip'ed on.

Thats bad news. Anyway, even then Apache seem not to start transfer to client
until the complete ruby script is executed. This means, there will be no
progress bar possible anyway.

Instead of copy the whole stuff, it creates a directory and symlinks every
file there in the current needed structure. This means, you don't have to do
anything to reinstall the scripts. You can continue to edit your files (I
have an auto-save every 2 seconds ;) and your developer site will be updated
immediatly. I thought maybe someone likes this too.
(You can do a "watch bash install_www myname" to achieve almost the same
effect, so remove the install_testserver if you don't like it.)
Ciao, Imi
