ssh

There are two documents you need to read, in order:

[gitolite and ssh][glssh] -- this explains how gitolite uses openssh's features to provide any number of virtual users over just one actual (unix) user, and so on
[ssh troubleshooting][sshts] -- this is a rather long document but as far as I know almost every known ssh related issue is in here. If you find something missing, send me an email with details.
