exporting schematic for latex and changing paper size in geda

Hi,

I am currently experimenting with geda and ngspice to simulate basic circuits (for a Circuits Analyses course). I drew a basic circuit in geda and exported it as netlist and got: ####################################################### $> gnetlist -v -g spice-sdb sch_1.sch -o sch_1.net ... (followed by lots of output) ... $> cat sch_1.net

• gnetlist -v -g spice-sdb -o sch_1.net sch_1.sch

*********************************************************

• Spice file generated by gnetlist *

• spice-sdb version 10.9.2004 by SDB -- *

• provides advanced spice netlisting capability. *

  *

********************************************************* V1 2 3 10V R2 1 3 50K R1 2 1 100K .END #######################################################

I was wondering:

1. How can I specify within geda which nodes I want monitored during a simulation? Or do I specify them on ngspice command line, or in the output .net file?
2. How do I export the schematic so that I can include it in a LaTeX file (as PS file perhaps)? I tried exporting it as PNG but I get the whole big 'sheet' with my tiny circuit in the middle.
3. How do I change the size of the 'sheet' or paper so that it is just big enough to accomodate my little circuits?

thanks,

->HS
