Yes, and to put in my 2-cents on the value of gschem alone, I use it to 
generate documentation for old and new projects for posterity and 
configuration control.  Most of these projects do not contain custom 
printed circuit boards.  I even use gschem to generate mechanical 
drawings of chassis and custom parts for these projects, at least until 
a mature open source 2D mechanical CAD program that runs under *nix 
comes along.  I have hundreds of gschem drawings and so far, zero PCB 
drawings.
