                    ---------------------------
This file should be used by the G4 example coordinator to briefly
summarize all major modifications introduced in the code and keep
track of all tags.

19th Nov 2009 Peter Gumplinger (fieldex-V09-02-00)
--------------------------------------------------
- Add new field example field05. This example checks the so-called 
  "spin-frozen" condition. There is a good article hep-ph/0012087v1.
  This article discusses about how to cancel the muon g-2 precession by
  applying an electric field.
  "Spin-frozen" happens when spin rotation cycle and muon rotation cycle
  are the same. The example will through a G4Exception if this is not the
  case.

29th Oct 2007 Peter Gumplinger (fieldex-V09-00-00)
--------------------------------------------------
- Add new field example field04 to exhibit the way
  overlapping fields may be handled in Geant4.

3rd May 2005  John Allison  (fieldex-V07-00-03)
------------------------------------------------
- Replaced vis manager with G4VisExecutive.

Dec 3rd, 2004 Gabriele Cosmo (fieldex-V06-02-00)
------------------------------------------------
- Implemented migration to <cmath>.
- Removed dependency on old PAI and XTR models in PhysicsList of
  field01/02/03 examples.

Mar 23rd, 2004 John Apostolakis (fieldex-V06-00-00)
---------------------------------------------------
- Group together fixes in: 
    field01    fieldex01-V06-00-00  and  
    field03    fieldex03-V06-00-00
  which fix common problem in SetField methods.
- Created.
