.SH SYNOPSIS
+
.B monkeysphere \fIcommand\fP [\fIargs\fP]
+
.SH DESCRIPTION
+
+MonkeySphere is a system to leverage the OpenPGP Web of Trust for ssh
+authentication and encryption. OpenPGP keys are tracked via GnuPG,
+and added to the ssh authorized_keys and known_hosts files to be used
+for authentication and encryption of ssh connection.
+
+\fBmonkeysphere\fP is the MonkeySphere client utility.
+
+.SH SUBCOMMANDS
+
+\fBmonkeysphere\fP takes various subcommands:
+.TP
+.B update-known_hosts [HOST]...
+Update the known_hosts file. For each specified host, gpg will be
+queried for a key associated with the host URI (see HOST URIs),
+querying a keyserver if none is found in the user's keychain. search
+for a gpg key for the host in the Web of Trust. If a key is found, it
+will be added to the host_keys cache (see KEY CACHES) and any ssh keys
+for the host will be removed from the user's known_hosts file. If the
+found key is acceptable (see KEY ACCEPTABILITY), then the host's gpg
+key will be added to the known_hosts file. If no gpg key is found for
+the host, then nothing is done. If no hosts are specified, all hosts
+listed in the known_hosts file will be processed. `k' may be used in
+place of `update-known_hosts'.
+.TP
+.B update-userids [USERID]...
+Add/update a user ID to the authorized_user_ids file. The user IDs
+specified should be exact matches to OpenPGP user IDs. For each
+specified user ID, gpg will be queried for a key associated with that
+user ID, querying a keyserver if none is found in the user's keychain.
+If a key is found, it will be added to the user_keys cache (see KEY
+CACHES) and the user ID will be added to the user's
+authorized_user_ids file (if it wasn't already present). `u' may be
+used in place of `update-userids'.
+.TP
+.B remove-userids [USERID]...
+Remove a user ID from the authorized_user_ids file. The user IDs
+specified should be exact matches to OpenPGP user IDs. `r' may be
+used in place of `remove-userids'.
+.TP
+.B update-authorized_keys
+Update the monkeysphere authorized_keys file. The monkeysphere
+authorized_keys file will be regenerated from the valid keys in the
+user_key cache, and the user's independently controlled
+authorized_keys file (usually ~/.ssh/authorized_keys). `a' may be
+used in place of `update-authorized_keys'.
+.TP
+.B gen-subkey KEYID
+Generate an `a` capable subkey. For the primary key with the
+specified key ID, generate a subkey with "authentication" capability
+that can be used for MonkeySphere transactions. `g' may be used in
+place of `gen-subkey'.
+.TP
+.B help
+Output a brief usage summary. `h' or `?' may be used in place of
+`help'.
+
+.SH HOST URIs
+
+Host OpenPGP keys have associated user IDs that use the ssh URI
+specification for the host, ie. "ssh://host.full.domain".
+
+.SH KEY ACCEPTABILITY
+
+GPG keys are considered acceptable if the following criteria are met:
+.TP
+.B capability
+For host keys, the key must have both the "authentication" ("a") and
+"encrypt" ("e") capability flags. For user keys, the key must have
+the "authentication" ("a") capability flag.
+.TP
+.B validity
+The key must be "fully" valid, and must not be expired or revoked.
+
+.SH KEY CACHES
+
+Monkeysphere keeps track of keys in key cache directories. The files
+in the cache are named with the format "USERID_HASH.PUB_KEY_ID", where
+USERID_HASH is a hash of the exact OpenPGP user ID, and PUB_KEY_ID is
+the key ID of the primary key. If the user/key ID combo exists in the
+Web of Trust but is not acceptable, then the file is empty. If the
+primary key has at least one acceptable sub key, then an ssh-style
+key, converted from the OpenPGP key, of all acceptable subkeys will be
+stored in the cache file, one per line. known_hosts style key lines
+will be stored in the host_keys cache files, and authorized_keys style
+key lines will be stored in the user_keys cache files. OpenPGP keys
+are converted to ssh-style keys with the openpgp2ssh utility (see `man
+openpgp2ssh').
