+    (description
+     "Verilator is invoked with parameters similar to GCC or Synopsys’s VCS.
+It ``Verilates'' the specified Verilog or SystemVerilog code by reading it,
+performing lint checks, and optionally inserting assertion checks and
+coverage-analysis points.  It outputs single- or multi-threaded @file{.cpp}
+and @file{.h} files, the ``Verilated'' code.
+
+The user writes a little C++/SystemC wrapper file, which instantiates the
+Verilated model of the user’s top level module.  These C++/SystemC files are
+then compiled by a C++ compiler (GCC/Clang/etc.).  The resulting executable
+performs the design simulation.  Verilator also supports linking its generated
+libraries, optionally encrypted, into other simulators.")
