thanks, that works just fine :) . I am writing some methods right now.
a last question maybe: how can I ouptut text on the command line from
within a function?
crit(...) and function_crit(...) don't seem to work, even when I include
the puppet functions using "... loadall" like said in the docs.
thanks in advance,
axel.
