 - modified requirements file for future use of the new package GaudiPI.

================= RootHistCnv v9r5 =====================================
! 2005-08-15 - Hubert Degaudenzi
 - patch #506. Creating H2D and H3D histograms (function
   createPersistent) was creating wrong values for weights in some
   cases. This patch removes all the implementation code and calls the
   Aida Root histogram converter (from pi) instead (Stephan Roiser).
	Remarks:
	-> this fix adds a dependency on PI in RootHistConv
	-> it also calls the conversion routine for H1D (to be consistent)

 - RFileCnv.cpp: Fixed small bug concerning checking output level
   before printing (Leggett)

 - HxDCnv.cpp, PersSvc.cpp, RConverter.*: added the option to prefix
   histograms id with "h" when they are numerical (mandatoty for
   HBOOK). This faciliates the interaction with them from the ROOT
   application.
       RootHistSvc.ForceAlphaIds  = true;

================= RootHistCnv v9r2 =====================================
! 2004-07-05 - Pere Mato
 - requirements: changed to use the new LCGCMT interface packages

================= RootHistCnv v9r1p1 =====================================
! 2004-05-07 - Pere Mato
 - RConverter.cpp: Fixed a problem that affected reading histogram
   files from Windows. Probably due to ":" or "\" in file
   name. Replaced gDirectory->cd() by TFile::cd()

! 2003-01-14 - Charles Leggett
 - RNTuple.cpp deal with empty ntuples

================= RootHistCnv v9r0 =====================================

   This includes:
   - change to the new AIDA version 3.0.0
   - the modified histogram converter classes H1DCnv, H2DCnv, H3DCnv,
     each responsible now for conversion of the corresponding fixed and
     variable bin size histograms (classes H1DVarCnv, H2DVarCnv,
     H3DVarCnv removed)
 - Added setting of statistics for 1D, 2D, 3D histograms being made persistent

   reading of 1D variable bin size histograms and 2D fixed bin size
   histograms possible

- New package developed by Charles Leggett to support Histogram
  Persistency based on ROOTsupport. As far as the user is concerned,
  They need to add to their jobOptions.txt file the following lines:

// Specify Share Library for ROOT persistency support
ApplicationMgr.DLLs += "RootHistSvc";
// Specify ROOT or HBOOK persistency (HBOOK is default)
ApplicationMgr.HistogramPersistency = "ROOT";
// Specify Histogram Persistency Output File
HistogramPersistencySvc.OutputFile = "histo.rt"
