+  <longdescription>
+    NVC is a VHDL compiler and simulator. NVC supports almost all of VHDL-2008
+    with the exception of PSL, and it has been successfully used to simulate
+    several real-world designs. Experimental support for VHDL-2019 is under
+    development. NVC has a particular emphasis on simulation performance and
+    uses LLVM to compile VHDL to native machine code. NVC is not a synthesizer.
+    That is, it does not output something that could be used to program an FPGA
+    or ASIC. It implements only the simulation behaviour of the language as
+    described by the IEEE 1076 standard. NVC supports popular verification
+    frameworks including OSVVM, UVVM, and VUnit. See below for installation
+    instructions.
