// Revision 1.1.1.1  2001/05/18 23:14:06  mb
// Move from private repository to open source repository
//
// Revision 1.3  2001/05/05 00:59:17  rmurphy
// Adding darwin license headers
//
// Revision 1.2  2000/06/15 18:48:23  dmitch
// Snacc-generated source files, now part of CVS tree to allow for cross-platform build of snaccRuntime.
//
// Revision 1.1.1.1  2000/03/09 01:00:05  rmurphy
// Base Fortissimo Tree
//
// Revision 1.2  1999/03/21 02:07:32  mb
// Added Copy to every AsnType.
//
// Revision 1.1  1999/02/25 05:21:41  mb
// Added snacc c++ library
//
// Revision 1.8  1995/09/07 18:45:13  rj
// use AsnBoolTypeDesc instead of AsnTypeDesc (no real difference, it is the same type).
//
// Revision 1.7  1995/07/24  17:53:54  rj
// #if TCL ... #endif wrapped into #if META ... #endif
//
// changed `_' to `-' in file names.
//
// Revision 1.6  1995/02/18  19:17:19  rj
// add TRUE/FALSE for backwards compatibility.
//
// Revision 1.5  1995/02/18  12:41:31  rj
// a few more lines for the sake of backwards compatibility.
//
// Revision 1.4  1994/10/08  04:17:58  rj
// code for meta structures added (provides information about the generated code itself).
//
// code for Tcl interface added (makes use of the above mentioned meta code).
//
// virtual inline functions (the destructor, the Clone() function, BEnc(), BDec() and Print()) moved from inc/*.h to src/*.C because g++ turns every one of them into a static non-inline function in every file where the .h file gets included.
//
// made Print() const (and some other, mainly comparison functions).
//
// several `unsigned long int' turned into `size_t'.
//
// Revision 1.3  1994/08/31  23:32:13  rj
// use the bool built-in where applicable, and a replacement type otherwise.
//
// Revision 1.2  1994/08/28  10:00:45  rj
// comment leader fixed.
//
// Revision 1.1  1994/08/28  09:20:27  rj
// first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog.
