Changes in McStas v1.9.1, Mar 29, 2006

  General
  - Update release, mainly bugfixes plus a few other things

  Documentation
  - Component manual slightly updated according to adding/modification of components.

  Tools
  - mcgui: A few bugfixes. Note also that if you experience crashes when starting/running
    GNOME/Gtk2 applications, update your perl-Tk installation. Two ways to do this:
    1) Get the tarball from http://www.mcstas.org/download/Tk-804.027_gtk2_patch.tar.gz and
       install using 'perl Makefile.PL && make && make install'. 
    2) Do a 'make tk' in the McStas unpacked McStas source directory. This will download and
       install the tarball into your McStas system directory.

  Components
  - DiskChopper.comp - new disc chopper component. Chopper.comp made obsolete. 
    See mcdoc page / component manual for further details.
  - Guide.comp - reads reflectivity tables from disk.
  - Isotropic_Sqw - minor bugfixes, validated against PowerN, V_sample, etc.
  - PowderN - validated against Isotropix_Sqw, Squires, experimental data.

  WARNINGS
  - Because of rapid changes in the support software for McStas, the current release has support
    for only some releases of:

    * Scilab (Win32 and Unix) - pick release 4.0 if available or pick release 3.0 from , e.g. from
      http://www.scilab.org/download/index_download.php?page=oldReleases.html

    * Perl (Win32) - on Windows we only support Perl 5.6 - pick
      http://downloads.activestate.com/ActivePerl/Windows/5.6/ActivePerl-5.6.1.638-MSWin32-x86.msi

    * If you are running Unix with GNOME/Gtk2 applications, you may experience problems with mcgui
      crashing, please install updated perl-Tk as noted above.
