This is GSL, the GNU Scientific Library. It is still in early stages of development, but it is being placed on ftp://alpha.gnu.org/gnu/ in hopes that others might be interested in joining the project. See the NEWS file for recent developments. A test suite is available for most of the libraries. It can be invoked with "make check" in each directory. All tests can be run together with "make check" at the top level. If you run "make check" and get some failures, please see the KNOWN-PROBLEMS file. This file lists failures we already know about. If you get failures that are not mentioned in the KNOWN-PROBLEMS file, please report them. Until we have set up a separate bug reporting address, please report bugs to the GSL discussion list gsl-discuss@sourceware.cygnus.com If you are interested in participating in GSL development, please send mail to Mark Galassi -- rosalia@lanl.gov
