    (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.")
