    Author:     David Aspinall

   This file allows a standalone build of the PGIP abstraction module.

   This should be useful for building other tools, or as an aid to porting.

   A lot of Isabelle library code is pulled in, but only a few
   functions are actually used, and the libraries indicated "used
   directly" below could be replaced with other implementations.
