 +====== Icarus Verilog Glossary ======
 +<​code>​Throughout Icarus Verilog descriptions and source code, I use a
 +variety of terms and acronyms that might be specific to Icarus
 +Verilog, have an Icarus Verilog specific meaning, or just aren't
 +widely known. So here I define these terms.
 +LRM     - Language Reference Manual
 +    This is a generic acronym, but in the Verilog world we sometimes
 +    mean *the* language reference manual, the IEEE1364 standard.
 +PLI     - Programming Language Interface
 +    This is a C API into Verilog simulators that is defined by the
 +    IEEE1364. There are two major interfaces, sometimes called PLI 1
 +    and PLI 2. PLI 2 is also often called VPI.
 +UDP     - User Defined Primitive
 +    These are objects that Verilog programmers define with the
 +    "​primitive"​ keyword. They are truth-table based devices. The
 +    syntax for defining them is described in the LRM.
 +VPI     -
 +    This is the C API that is defined by the Verilog standard, and
 +    that Icarus Verilog partially implements. See also PLI.
 +VVM     - Verilog Virtual Machine
 +    This is the Icarus Verilog runtime that works with the code
 +    generator that generates C++.
 +VVP     - Verilog Virtual Processor
 +    This is the Icarus Verilog runtime that reads in custom code in a
 +    form that I call "VVP Assembly"​. See the vvp/ directory for
 +    documentation on that.
