The GNU SASL Library is a library that implements the Simple
Authentication and Security Layer (SASL) framework and some plugins.

The GNU SASL Library is licensed under the GNU Lesser General Public
License (LGPL) version 2.1 (or later).  See the file COPYING.LIB.  The
GNU project typically uses the GNU General Public License (GPL) for
libraries, and not the LGPL, but for this project we decided that we
would get more help from the community if we used the LGPLv2.1+, as
other free SASL implementations exists.  See also
<http://www.gnu.org/licenses/why-not-lgpl.html>.

Some parts, such as the gnulib self-tests (gltests/) are licensed
under the GNU General Public License (GPL) version 3.0 (or later).
See the file COPYING.

The manual is not included in this directory, see the full GNU SASL
archive.
