          + Geometry close to that from MCNPX
          + 2012 cold brightness
          + A much easier-to-use definition of geometry, allowing to
            specify the instrument position within a 60-degree sector

  <title>  July 24th, 2011: McStas 1.12c on Mac OS X Lion - hold your horses!</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.11</date>
  <description><![CDATA[

   The newly released Mac OS X 10.7 Lion includes a lot of nice upgrades
   from Apple - including some that break the tool-layer and mpi support
   for McStas:

   Symptom Cause
   mpi compile fails The system-provided mpi is not detected by the McStas
   configure script
   mcgui does not start mcgui requires perl::Tk, and the version we ship
   with McStas 1.12c explicitly requires perl 5.8, which has been removed
   from Lion
   mcplot does not plot For plotting, we rely on the SciKarl port of
   pgplot, perl::PDL and perl::PGPLOT. The SciKarl perl modules are built
   for perl 5.8 which has been removed from Lion

   In conclusion: If you want to keep a functional McStas install, please
   do not upgrade to Lion yet!]]></description>

  <title>  March 21st, 2013: Supplemental mcdisplay / Python package available</title>
  <link>http://www.mcstas.org</link>
  <date>5 McNews.5</date>
  <description><![CDATA[

   As of today, our Python-based mcdisplay package is available via either
     * apt-get install mcstas-tools-python-mcdisplay-2.0 on debian-like
       systems (if you added our .deb repository)
     * yum install mcstas-tools-python-mcdisplay-2.0 (if you added our
       .rpm repository)
     * - Or for manual download from our Download share

   To make use of the package, you need an x3d browser on your system - we
   recommend Instant Player developed by the Fraunhofer Gesellschaft.

   If you want to run a combination of our Python and Perl tools - have a
   look at File->Preferences in mcgui (see graphic below)

   The allows you to define the commands executed from mcgui for
   running/compiling (mcrun), visualizing (mcdisplay) or plotting data
   (mcplot) from your instrument. The naming convention is this one (not
   completely obvious, sorry):

   [mcgui-2.0-prefs.png]

   Unix (Linux / Mac OS):

   Tool      Perl          Python
   mcrun     mcrun-2.0     mcrun-2.0-py
   mcplot    mcplot-2.0    mcplot-2.0-py (chaco) or mcplot-2.0-matplotlib
                           (matplotlib)
   mcdisplay mcdisplay-2.0 mcdisplay-2.0-py

   Windows:
   Tool      Perl         Python
   mcrun     mcrun.pl     mcrun-py.bat
   mcplot    mcplot.pl    mcplot-chaco.bat (chaco) or mcplot-matplotlib.bat
                          (matplotlib)
   mcdisplay mcdisplay.pl mcdisplay-py.bat

   To save your preferences for the next McStas run, use File->Save
   configuration:
     * On Unix (Linux / Mac OS) systems to your user's $HOME/.mcstas/
       folder
     * On Windows directly to the system
       c:\mcstas-2.0\lib\mcstas-tools-2.0\perl folder]]></description>

  <title>  March 15th, 2013: (Re-)enable syntax highlighting in mcgui-2.0 on Ubuntu</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.6</date>
  <description><![CDATA[

   If your mcgui editor on Ubuntu is missing it's usual syntax
   highlighting, either
     * If you installed mcstas via our Debian repository, simply run this
       command in a terminal:
sudo apt-get install libtk-codetext-perl
     * If you installed mcstas "manually" by downloading our set of
       Debian packags from the download page, first download our
       64 bit or 32 bit libtk-codetext-perl package. Secondly
       install it using]]></description>

  <title>  March 15th, 2013: Component docs are back on website, plus an mcdoc hint</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.8</date>
  <description><![CDATA[

   As several people have pointed out, the component docs were removed
   from the website in connection with the release of McStas 2.0.

   They are now back at http://www.mcstas.org/download/components/

   I have further become aware that the McStas 2.0 distribution - at least
   in the debian packages - was missing a call to mcdoc for generating the
   same pages there

   To remedy that problem, please:
cd /usr/local/lib/mcstas-2.0
sudo mcdoc -t

   - which should bring back the docs on your local machine.

   I am working my way down a list of other annoyances and aim to release
   a McStas 2.0a with various issues fixed in a few weeks. Please let me
   know if you found any issue that I can correct in the next release.]]></description>

  <title>  March 12th: Respin of McStas 1.12c dmg for OS X Lion</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.9</date>
  <description><![CDATA[

   As reported to mcstas-users@mcstas.org, the McStas 1.12c dmg for OS
   X Lion was unfortunately corrupt. A new version of the image has been
   uploaded. The filename is slightly different to be able to
   distinguish the image from older downloads you may have.]]></description>
