+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. Key feature of the program is
+its drawing engine written in C and using directly the Xlib drawing
+primitives; this gives very good speed performance, even on very big
+circuits. The user interface is built with the Tcl-Tk toolkit, tcl is
+also the extension language used.  - hierarchical schematic drawings,
+no limits on size - any object in the schematic can have any sort of
+properties (generics in VHDL, parameters in Spice or Verilog) - new
+Spice/Verilog primitives can be created, and the netlist format can
+be defined by the user -tcl extension language allows the creation
+of scripts; any user command in the drawing window has an associated
+tcl comand - VHDL / Verilog / Spice netlist, ready for simulation -
+Behavioral VHDL / Verilog code can be embedded as one of the properties
+of the schematic block,

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
