-===== 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/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.
-The current version (as of Jnue 23rd 2010) is Casa 3.0.2 .
-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 ''$HOME/.casarc'' file that contains the directory where your version of the tables are. For instance:<code>
-measures.directory: /opt/casacore/data
-</code>
-==== Casacore ====
-We make available official releases of casacore for people that like to develop against stable libraries of casacore. The latest development version of casacore is available in the [[#LofIm]] package described below.
-For documentation, etc., see the casacore homepage: http://code.google.com/p/casacore/
-Casacore uses the IERS measures tables that are in ''/opt/casacore/data''; this location is linked in during the build. If you want to use custom IERS tables, you'll have to make a ''$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 1.3.0
-  * [[http://www.scipy.org/|SciPy]] -> version 0.7.1
-  * [[http://matplotlib.sourceforge.net/|matplotlib]] -> version 0.99.1.1
-  * [[http://www.stsci.edu/resources/software_hardware/pyfits|PyFits]] -> version 2.2.2
-  * [[http://rhodesmill.org/pyephem/|PyEphem]] -> version 3.7.3.4
-  * [[http://pyfftw.berlios.de/|PyFFTW]] -> version 0.2
-  * [[http://www.pytables.org/|PyTables]] -> version 2.1.2
-  * [[http://h5py.alfven.org/|H5Py]] -> Version 1.2.1
-  * [[http://setiathome.berkeley.edu/~aparsons/aipy/aipy.cgi|Aipy]] -> Version 0.9.1
-==== LUS ====
-The LUS stands for Lofar User Software. It is a part of the User Software Groups (USG) software package. The main packages that are build are the DAL (Data Access Layer) and the Pulsar package (TEMPO, PResto, etc.). 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 available on all cluster nodes. To activate it type:<code>
-> use LUS
-</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.
