+    (description "Icarus Verilog is a Verilog simulation and synthesis tool.
+It operates as a compiler, compiling source code written in Verilog
+(IEEE-1364) into some target format.
+For batch simulation, the compiler can generate an intermediate form called
+vvp assembly.
+This intermediate form is executed by the ``vvp'' command.
+For synthesis, the compiler generates netlists in the desired format.")
