Hi Chris,

many thanks for the quick response and the valuable hint for the wirble 
gem.
As I have to leave now, it will be the first thing that I try tomorrow 
and give feedback.

As for Gems configuration.
Do you have any idea where and how I would have to put our proxy 
informations (url, port, credentials) so that I could query Internet 
Gems repositories?
I tried the -p http://proxy_user:proxy_passwd@our.proxy.url:proxy_port 
switch with the gem list command but it didn't work.
So I sought for a config file like I am used to with the Perl 
CPAN/Config.pm
but couldn't find something comparable beneath the gems tree.

I start to like Ruby.
I only need to get used to Ruby idioms and doing things the Ruby way
instead of taking over habits from Perl.
But since I so far lack knowledge of all the methods
(although some_object.methods.sort in irb is a tremendous help) it takes 
some
time to discover.
