Fri Jan 19 17:56:20 CET 2001 hannes:
* mod, div for intvec fixed
* highcorner for global case fixed
* highcorner for qring fixed
Tue Feb  1 09:33:35 MET 2000 hannes: summary of changes
* lift changed: - uses interanlly a different algorithm 
                  (for SB and NON-SB unified)
                - can be used with an optional 3rd argument (a matrix name),
                  if given, the "matrix of units" will be stored in it
* new command: division (extension of lift)
     division(M,SM) returns a list (T,U,R) with SM*U+R=M*T
* new monomial ordering (internal change only): 
   use of inline function instead of a function pointer
   (possible point for difficulties: mcompSchrB(polys.cc), pSetSchreyerOrdM
   (polys.cc))
* new Library: 
   spectrum.lib: interface to Stefan Endrass' spectrum routines
   (Stefan Endrass/H.Schoenemann)
   (still incomplete, requires a "special" Singular)
* new Library: 
   CaMuReg.lib: PROCEDURES FOR COMPUTING CASTELNUOVO-MUMFORD REGULARITY
   Authors:I.Bermejo/Ph.Gimenez/G.-M.Greuel
   (not included in the documemtation, not included in the tests)
* new command: hres 
    - computes a free resolution of an ideal using Hilbert-driven algorithm
* new commands: convhull, simplex (M.Wenk)
  (not documented, not included in the documemtation, not included in the tests)
