XCircuit is a powerful open source schematic capture program. It has most of the features of a general purpose drawing package and includes a symbol library facility that can be used to store user defined schematic symbols. Schematics, libraries of vacuum tube, flow charts, chemical diagrams, and even musical scores may be created with XCircuit by loading the freely available symbol libraries. A mathematical symbol typesetting capability is included in the program. XCircuit uses the PostScript language for its output and library files. The PostScript created by XCircuit is human readable which makes manual editing possible.
