[-- Attachment #1: Type: text/plain, Size: 260 bytes --]
Please find attached a patch that enables the configuration of some of
openssh's forwarding options.
These changes are based off of the existing x11-forwarding? option that
already exists in ssh.scm.
Also, I have added some documentation for these options.
