+===== Descriptions of Packages =====
+==== Casa ====
+This is the NRAO developped package that provides Graphical interfaces like those available in the old AIPS++ packages. It provides the following useful tools (see directory ''/opt/cep/Casa/bin''):
+  * ''casabrowser'' -> A table browser (much like the old glish-based browser)
+  * ''casaplotms'' -> A tool to make 2-D plots of data in a MS
+  * ''casaviewer'' -> Visualizer
+  * ''casapy'' -> Casa's Python interface.
+Extensive documentation can be found [[http://casa.nrao.edu/|on this NRAO-hosted webpage]].
+  * The release and helpdesk can be obtained from http://my.nrao.edu. Versions are available for Linux and Mac OSX 10.5 and 10.6.
+  * Details about the release including new capabilities, release notes, and the full user reference and cookbook can be found at the CASA home page: http://casa.nrao.edu
+  * We are also pleased to announce the creation of a new CASA wiki with fully annotated tutorials and tips: http://casaguides.nrao.edu. More guides covering a wider range of data possibilities will be added over time.
+  * Casa has NO support for the LOFAR storagemanager used to create raw LOFAR datafiles.
+The current version (as of May 29th 2013) is Casa 4.0.1.
+Casa uses the IERS measures tables that are provided by the distribution; this is linked in with the code. If you want to use custom IERS tables, you'll have to make a ''$HOME/.casarc'' file that contains the directory where your version of the tables are. For instance:<code>
+measures.directory: /opt/casacore/data
+</code>
+==== Casacore ====
+We make available official releases of casacore for people that like to develop against stable libraries of casacore. The latest development version of casacore is available in the [[#LofIm]] package described below. The current release is version 1.2.0.
+For documentation, etc., see the casacore homepage: http://code.google.com/p/casacore/
+Casacore uses the IERS measures tables that are in ''/opt/casacore/data''; this location is linked in during the build. If you want to use custom IERS tables, you'll have to make a ''$HOME/.casarc'' file that contains the directory where your version of the tables are. For instance:<code>
+measures.directory: /users/foobar/IERS
+</code>
+==== LofIm ====
+The package LofIm (Lofar Imaging) consists of the following subpackages:
+  * casacore
+  * casarest
+  * pyrap
+  * LOFAR
+  * ASKAPsoft
+All these are build every night in a single go, with source code extracted from each package's source repository. Activating the LofIm package ensures that you will have a consistent set of libraries and executables.
+To activate it on commandline use:
+  > use LofIm
+This will activate the version that was build last night. It will add all settings needed to use the subpackages toyour ''PATH'', ''PYTHONPATH'' and ''LD_LIBRARY_PATH'' environment variables.
+As all of the individual subpackages are in a development phase, we **cannot** guarantee that each nightly build is bugfree, or even that is has succeeded. Therefore, we keep a 'buffer' of previous builds for a week. This ensures that if a nightly build has failed, you can use a (working) previous build. To activate a previous build on commandline use:
+  > use LofIm <day> (e.g., use LofIm Wed)
+If the problem that caused a build to fail has not been solved in a week's time, you will not be able to use the package until it has been fixed. In due time we will implement a system with a release policy, that will enable you to use 'stable' versions of these libraries.
+LofIm uses the IERS measures tables that are in ''/opt/casacore/data''; this is linked in with the code. If you want to use custom IERS tables, you'll have to make a ''$HOME/.casarc'' file that contains the directory where your version of the tables are. For instance:<code>
+measures.directory: /users/foobar/IERS
+</code>
+==== GDL ====
+The GDL package contains the following subpackages:
+  - [[http://gnudatalanguage.sourceforge.net/|gdl (Gnu data language)]]
+  - [[http://www.gnu.org/software/gsl/|gsl (GNU Scientific Library)]]
+  - [[http://plplot.sourceforge.net/|plplot]]
+These work together and form a useful packages used by the Pulsar group.
+==== Pythonlibs ====
+We have made available several useful Python modules. These can be activated with a single command:
+  > use Pythonlibs
+(see [[public:lle|this page]] for information on how to activate at login time). The Pythonlibs currently contain:
+  * [[http://numpy.scipy.org/|Numpy]] -> version 1.6.2
+  * [[http://www.scipy.org/|SciPy]] -> version 0.7.1
+  * [[http://matplotlib.sourceforge.net/|matplotlib]] -> version 1.1.0
+  * [[http://www.stsci.edu/resources/software_hardware/pyfits|PyFits]] -> version 3.1.1
+  * [[http://rhodesmill.org/pyephem/|PyEphem]] -> version 3.7.3.4
+  * [[http://pyfftw.berlios.de/|PyFFTW]] -> version 0.2
+  * [[http://www.pytables.org/|PyTables]] -> version 2.3.1
+  * [[http://h5py.alfven.org/|H5Py]] -> Version 2.0.1
+  * [[http://casper.berkeley.edu/astrobaki/index.php/AIPY|Aipy]] -> Version 1.0.1
+  * [[http://www.astro.rug.nl/software/kapteyn/|Kapteyn]] -> Version 2.2
+  * pywcs -> Version 1.10-4.7
+  * numexpr -> Version 1.4.2
+==== LUS ====
+The LUS stands for [[public:user software:user software|Lofar User Software]]. The main packages that are build are
+  * the [[public:user software:DAL|Data Access Library]] (DAL),
+  * the Pulsar package (TEMPO, Presto, pulp, etc.),
+  * the CR-Tools.
+Information about these packages can be obtained by Lars Baehren (DAL, build system) or Anastasia Alexov (Pulsar software).
+The LUS is build on a daily basis on lfe001 and lhn001 and is available on all cluster nodes. To activate it type:<code>
+> use LUS
+or
+> use LUS <day>
+</code>
+It will add items to the ''PATH'', ''LD_LIBRARY_PATH'', ''PYTHONPATH'' variables, and add ''LOFARSOFT'', ''PRESTO'' and ''TEMPO'' env. vars. to your login session.
