The  initial  release   of  CUTE,  a  widely  used   testing  environment  for
optimization  software,  was described  in  Bongartz,  Conn,  Gould and  Toint
(1995).  A  new version,  now known as  CUTEr, is presented.  Features include
reorganisation  of  the   environment  to  allow  simultaneous  multi-platform
installation, new tools  for, and interfaces to, optimization  packages, and a
considerably simplified and entirely automated installation procedure for UNIX
systems. The  environment is fully  backward compatible with  its predecessor,
offers support  for Fortran 90/95 and a general  C/C++ Application Programming
Interface. The  SIF decoder, formerly a  part of \cute, has  become a separate
tool, easily  callable by various  packages. It features simple  extensions to
the SIF  test problem format and  the generation of files  suited to automatic
differentiation packages.
