  $Log: ApParseCat.h,v $
  Revision 1.4  1996/10/10 16:45:18  wenger
  Changed function names, etc., in ApParseCat.c to get rid of name clashes
  when Donko puts transformation engine code into DEVise.

  Revision 1.3  1996/04/30 15:31:39  wenger
  Attrproj code now reads records via TData object; interface to Birch
  code now in place (but not fully functional).

  Revision 1.2  1996/04/25 19:25:12  wenger
  Attribute projection code can now parse a schema, and create the
  corresponding TData object.

  Revision 1.1  1996/04/22 18:01:48  wenger
  First version of "attribute projection" code.  The parser (with
  the exception of instantiating any TData) compiles and runs.
