// Revision 1.6 1997/02/16 20:25:45 rj
// check-in of a few cosmetic changes
//
// Revision 1.5 1995/07/24 17:35:52 rj
// ``#error "..."'' instead of ``#error ...''.
//
// changed `_' to `-' in file names.
//
// Revision 1.4 1995/02/18 16:45:53 rj
// let cpp choose a 32 bit integer type.
//
// Revision 1.3 1994/10/08 04:18:09 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 1.2 1994/08/28 10:00:56 rj
// comment leader fixed.
//
// Revision 1.1 1994/08/28 09:20:43 rj
// first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog.
