XCircuit is a program for drawing publishable-quality electrical circuit 
schematic diagrams and related figures, and produce circuit netlists through 
schematic capture.  XCircuit regards circuits as inherently hierarchical, and 
writes both hierarchical PostScript output and hierarchical SPICE netlists. 
Circuit components are saved in and retrieved from libraries which are fully 
editable.  XCircuit does not separate artistic expression from circuit 
drawing; it maintains flexiblity in style without compromising the power 
of schematic capture.

XCircuit is flexible enough to be used as a generic program for drawing just 
about anything, and is competitive with powerful programs such as xfig. 
It is especially good for any task requiring repeated use of a standard set 
of graphical objects, including architectural drawing, printed circuit board 
(PCB) layouts, and music typography.
