-- | FFI bindings to libssh2 SSH2 client library (http://libssh2.org/)
--   
--   This package provides FFI bindings for SSH2 client library named
--   libssh2.
--   
--   As of version 0.2 all blocking is handled in Haskell code rather than
--   in C code. This means that all calls are now interruptable using
--   Haskell asynchronous exceptions; for instance, it is now possible to
--   use <a>System.Timeout</a> in combination with "libssh2".
--   
--   <i>Note on usage on Windows</i>: On Windows you MUST compile your
--   executable with <tt>-threaded</tt> or <a>libssh2</a> will NOT work. We
--   have tested <a>libssh2</a> on Windows using <a>http://mingw.org/</a>,
--   with <a>http://www.openssl.org/</a> and <a>http://libssh2.org/</a>
--   compiled from source (be sure to pass the <a>shared</a> option to the
--   configure script for <a>openssl</a> to enable the shared libraries).
