    longDescription = ''
      Xschem is a schematic capture program, it allows creation of
      hierarchical representation of circuits with a top down approach.
      By focusing on interfaces, hierarchy and instance properties a
      complex system can be described in terms of simpler building
      blocks. A VHDL or Verilog or Spice netlist can be generated from
      the drawn schematic, allowing the simulation of the circuit.
