gEDA-user: gschem example?

[Zoran Spasojevic]

I am new to gschem and I am trying my first example of a passive filter 
with gschem.
I get lots of errors when I run
gnetlist -g drc2 test.sch -o drcout.txt
Is there a simple example posted on the Internet of a gschem file
(preferably a passive filter) that passes this test?
Thanks,
Zoran
