gEDA-user: newbie questions

[Ron Crummett <rcrummett@xxxxxxxxxx>]

Hi all -

I am an electrical engineering student and will be taking a class in 
communication circuits next semester.  My teacher has told me that we 
will be working a lot with WinSpice and, well, those first three little 
letters tell me that I probably won't be doing much of THAT on my Debian 
machine.  So...

I am looking for a Linux-compliant freeware circuit simulation program 
similar to WinSpice.  I have stumbled across gEDA in my search and it 
looks like it might be the answer, particularly ngspice.  Problem is, I 
have no idea of how to use these programs and all the documentation I 
find on the gEDA pages seem to be for the PCB layout programs and such.

So my questions are:
-is ngspice what I am looking for?  A Linux circuit simulator?
-where can I find documentation for ngspice?

(the second question is, of course, assuming the answer to the first is 
affirmative.)

Thanks,

-Ron
