wl for Debian
------------------

The following setting enables you to run Wanderlust as a default mail
user agent of emacsen.

    (if (boundp 'mail-user-agent)
        (setq mail-user-agent 'wl-user-agent))
    (if (boundp 'read-mail-command)
        (setq read-mail-command 'wl))

To use SSL/TLS, install the ca-certificates package and the gnutls-bin
package to use the gnutls-cli command.

For emacs24 or later versions, built-in gnutls.el is used.
(If gnutls.el is not installed, tls.el or ssl.el is used.)

e.g.
    (setq gnutls-verify-error t)
    (setq gnutls-algorithm-priority "SECURE:-VERS-SSL3.0")

If you encounter an SSL/TLS connection failure, execute gnutls-cli
directly to diagnose.  See also the manual of gnutls-cli.

For more information, see the Info documents.
