SCRAM-SHA-1/256/512 support for Perl library Authen::SASL

 The Authen::SASL::SCRAM distribution adds SCRAM authentication mechanisms to
 Authen::Perl. By installing this library existing Perl applications depending
 on Authen::Perl are instantly extended with these authentication mechanisms
 when they use the Perl backend (as opposed to the other available backends
 [XS and Cyrus]).
 .
 The library was written to enhance the "sendxmpp" program which is included
 in Debian under a package by the same name, because 99% of all XMPP servers
 don't offer any of the authentication mechanisms supported by the standard
 Authen::SASL library anymore (PLAIN, CRAM-MD5, DIGEST-MD5, LOGIN; most don't
 offer GSSAPI).
