/* The API version is maintained (independently from the Python version)
   so we can detect mismatches between the interpreter and dynamically
   loaded modules.  These are diagnosticised by an error message but
   the module is still loaded (because the mismatch can only be tested
   after loading the module).  The error message is intended to
   explain the core dump a few seconds later.

   The symbol PYTHON_API_STRING defines the same value as a string
   literal.  *** PLEASE MAKE SURE THE DEFINITIONS MATCH. ***

   Please add a line or two to the top of this log for each API
   version change:

   30-Jul-1996	GvR	Slice and ellipses syntax added

   23-Jul-1996	GvR	For 1.4 -- better safe than sorry this time :-)

   7-Nov-1995	GvR	Keyword arguments (should've been done at 1.3 :-( )

   10-Jan-1995	GvR	Renamed globals to new naming scheme

   9-Jan-1995	GvR	Initial version (incompatible with older API)
