POLYLIB 4.12
============
released apr-20-99, Vincent Loechner
- Reorganized the directories and improved the Makefiles.
  Build dynamic libraries, added an automatic installation procedure.
- some minor changes in the code.

POLYLIB 4.10
============
released feb/mar-99, Vincent Loechner & Adrian Slowik
- integrated Adrian Slowik's GNU-MP port of ehrhart to eliminate all
  overflows. Vincent wrote the integration to the standard version :
  if 64 (or 32) bits are not enough for a computation, everything is
  converted into MP-numbers and the computations go on. The systematic
  use of GNU-MP would slow down substantifically the program.
  Many thanks to :
  Adrian Slowik, Universitaet-GH Paderborn, adrian@uni-paderborn.de
- corrected an old bug in Matrix_Read (!). Test/e3 and others did not pass.
  replaced atoi by strtol.

POLYLIB 4.0b3
=============
dec-98, Vincent Loechner
- quick workaround for a bug in the initial enumeration for computing
  ehrhart polynomials. This routine still needs to be rewritten to
  eliminate the 'degenerated domain' message. To be done soon.

POLYLIB 4.0b2
=============
released 17-oct-98, Vincent Loechner
- corrected a bug in PolyhedronEnumerate to treat polyhedra
  with 0 parameters.

POLYLIB 4.0b1
=============
27-mar-98, Vincent Loechner and Doran Wilde
- reorganization of files : Obj.OSTYPE directories,
  creation of libraries (.a)
  the new directory structure is :
  ./           sources for the polylib
  ./Test       test suite
  ./arithlib   arithmetic library (CRI, ENSMP)
  ./Obj.*      one of these directory is created for each system
               and for each type of integer (type 'Value': 32/64 bits)

POLYLIB 4.0
=============
nov-97, Olivier Albiez
- polyhedron.c : calls to arithmetic library from CRI (ENSMP Paris)
  (authors: Francois Irigoin, Remi Triolet, Fabien Coelho)
feb-98, Vincent Loechner
- polyparam.c and ehrhart.c : calls to arithmetic library.
- some bug corrections

POLYLIB 3.0b9
=============
released 16-jul-97, Vincent Loechner
- Ehrhart polynomials evaluation functions (Emmanuel Jeannot)
- treat polyhedra with 0 parameters (Xavier Redon)

POLYLIB 3.0b8
=============
released on http://icps.u-strasbg.fr/~loechner/polylib: 16-jun-97
- some bug corrections
- Polyhedron_Enumerate returns a value (which is a nice thing :)
