gsl: The GNU Scientific Library
===============================

Description
-----------

The GNU Scientific Library

Website: http://www.gnu.org/software/gsl/

From the website above: The GNU Scientific Library (GSL) is a numerical
library for C and C++ programmers. It is free software under the GNU
General Public License.

The library provides a wide range of mathematical routines such as
random number generators, special functions and least-squares fitting.
There are over 1000 functions in total with an extensive test suite. If
the variable SAGE_CHECK is exported to the value "yes" when building
Sage, GSL's test suite is run.

Upstream Contact
----------------

-  http://www.gnu.org/software/gsl/

GSL mailing lists:

-  Bug-gsl <bug-gsl@gnu.org> mailing list -- bug reports for the GNU
   Scientific Library should be sent to bug-gsl@gnu.org

-  Help-gsl <help-gsl@gnu.org> users mailing list -- for questions about
   installation, how GSL works and how it is used, or general questions
   concerning GSL.

-  Info-gsl <info-gsl@gnu.org> mailing list -- announcements of new
   releases
   are made there.

Dependencies
------------

-  None - GSL does not depend on any other Sage package to compile, link
   and pass all of GSL's self-tests. Despite that fact, BLAS is listed
   as
   a dependency. (It comes with its own CBLAS implementation that is
   e.g.
   used when running the GSL test suite during installation; however,
   the
   Sage library only uses it as a fall-back, if e.g. BLAS library is not
   present.)
