// Description:
//  Standard include file to contain global "fixes"
//      and type definitions
//
//      This file is intended to be included by _lots_ of others
//      so should stay very light-weight.  In particular, definitions
//      of static variables are not appropriate here, as they
//      will allocate memory in every BaBar object file.
//
// Environment:
//  Software developed for the BaBar Detector at the SLAC B-Factory.
//
// Author List:
//  David Quarrie
//      Bob Jacobsen (added F90 interface types, fixed bool, Mar 19,95)
//  Forest Rouse (added pi, bznom, chisq_undef, and epsilon)
//      Abi Soffer (added BbrLorentzVector)
//      A. De Silva (moved macros from Framework/AppModule.hh. Jan 29,99)
