lepton-schematic is a schematic capture application in the Lepton
toolset. It is mostly used for interactive creation of electronic
schematics and symbols, though you can do some other
graphical work in it, for example, draw block diagrams. Schematics
represent electronic circuits, and symbols stand for their logical
blocks such as components or subcircuits. The connections between the
blocks are represented by nets (wires). Component symbols can
be obtained either from a standard Lepton component library, from some net resources, or created by the user.
After creation, schematics may be printed, converted to several image formats, including PDF, or exported to several netlist formats for processing by other tools.
