    (description
     "LDC is a compiler for the D programming Language.  It is based on the
latest DMD frontend and uses LLVM as backend.  LLVM provides a fast and modern
backend for high quality code generation.  LDC is released under a BSD license
with exceptions for the DMD frontend and code from GDC.  The development takes
place mostly on x86-32 and x86-64 Linux and that is where LDC works best.")
