+   (description
+    "GNU SASL is an implementation of the Simple Authentication and Security
+Layer framework and a few common SASL mechanisms. SASL is used by network
+servers (e.g., IMAP, SMTP) to request authentication from clients, and in
+clients to authenticate against servers.
+
+GNU SASL consists of a library (libgsasl), a command line utility (gsasl)
+to access the library from the shell, and a manual. The library includes
+support for the framework (with authentication functions and application
+data privacy and integrity functions) and at least partial support for the
+CRAM-MD5, EXTERNAL, GSSAPI, ANONYMOUS, PLAIN, SECURID, DIGEST-MD5,
+SCRAM-SHA-1, SCRAM-SHA-1-PLUS, LOGIN, and NTLM mechanisms.
+
+The library is portable because it does not do network communication by
+itself, but rather leaves it up to the calling application. The library is
+flexible with regards to the authorization infrastructure used, as it
+utilises callbacks into the application to decide whether an user is
+authorised or not.
+
+The gsasl package distribution includes the library part as well,
+so there is no need to install two packages.")
