XCircuit 2.2.1
XCircuit is a UNIX/X11 program for drawing publishable-quality electrical circuit schematic diagrams and related figures.

Graphically object-based, it can 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 layouts, and music typography.
