/// The <a href="https://github.com/casacore/casacore">casacore</a> package
/// contains the core libraries of the old
/// <a href="http://aips2.nrao.edu">AIPS++/CASA</a> package. This split
/// was made to get
/// a better separation of core libraries and applications.
/// <a href="http://casa.nrao.edu">CASA</a> is now built on top of casacore.
///
/// The system consists of a set of layered libraries (packages) which can
/// be seen best on the <a href="modules.html">Modules page</a>.
/// <br>
/// Included is a library (using Boost-Python) to convert the basic casacore types
/// (e.g., Array, Record) to and from python. Build of this library is optional.
/// <br>
/// This library is used in the package
/// <a href="https://github.com/casacore/python-casacore">python-casacore</a>
/// (previously pyrap) that offers a
/// high level <a href="http://www.python.org">Python</a> binding to
/// the casacore functionality.
/// The documentation of the python-casacore packages can be found
/// <a href="http://python-casacore.readthedocs.org/">here</a>.
///
/// The main features of AIPS++/CASA are:
/// <ul>
/// <li>\ref casa : Core functionality and data types like Array and Record.
/// <li>\ref scimath : N-dim functions with auto-differentiation and linear or non-linear
/// fitting.
/// <li>\ref tables : Table data system supporting N-dim arrays with advanced querying.
/// <li>\ref measures : Values in astronomical reference frames using
/// physical units (<a href="group__Quanta__module.html">Quanta</a>).
/// <li>\ref ms : MeasurementSets for storing data in the UV-domain.
/// <li>\ref images : N-dim images in world coordinates with various analysis operations.
/// </ul>
/// Casacore <a href="../notes/notes.html">notes</a> describe
/// some parts of the system in more detail.
///
