Send commands to me by /msg, or say them in channel with ! in front.

!help
help             gives an overview and lists the topics &c
help <command>   gives help on a command
help <opt>       gives help on an option
help <topic>     gives help on an additional topic

!seen
seen <nick>
 Tells you or the channel when I last saw that nick in
 use.  When the nick is next used, I'll tell them you asked.

!summon
summon <username>
 Invites a logged-on user onto IRC.  If the user is not logged on
 you'll be told.  Target users can change this (eg, to disable it)
 by reconfiguring the userv service `irc-summon'.  See ~ian/.userv.

!convert
convert <number> <unit>
 Converts the specified quantity into SI units.  Units that are
 understood are any understood by units(1) and also
   kelvin celsius fahrenheit    (convert to celsius or kelvin)

!ops
ops             on channel
ops <channel>   (privately)
 Asks me to give you channel operator privilege.  You must have
 identified yourself (see `help identification').

!oplist
oplist [<chan>]                      show chop list
oplist [<chan>] + <nick> <nick> ...  add nicks to chop list
oplist [<chan>] - <nick> <nick> ...  remove nicks from chop list
oplist [<chan>] = <nick> <nick> ...  set chop list
 Configures the list of who may use the `ops' command.  You must be
 on the oplist yourself to do this.  If you op me on a channel I'll
 automatically add you to the oplist if you have identified yourself.

!identify
You must identify yourself to change your settings and to use channel
management commands.  In ircII on chiark, just say `/blight-id'.  For
other clients, see `help identpass'.  Once you are identified you can
then register new nicks, change settings, etc. - so long as you
remain on a channel that I'm on too.  (See also `help invite'.)

!identpass
identpass <username> <password>
 Identification, for example with /blight-id, is actually done with
 `identpass', which feeds the md5sum of the password to `userv
 <username> irc-identpass <nick>'.  That must exit 0 if all is well.

!invite
If you invite me to a channel I'll join it.

!register
register            register your nick (or make it secure)
register delete     delete your nick registration
register insecure   register your nick insecurely
 I only store settings for registered nicks.  For `insecure' nicks
 anyone who currently holds that nick can change its settings,
 including securing it to their username.  `secure' nicks can only
 have their settings changed by the user to which they are
 registered, after identifying themselves (see `help identify').

!set
set                  show your current settings
set <option>         show the current setting of <option>
set <option> <value> set <option> to <value>
 See also `help register' and `help ident'.  See just `help' for the
 list of options, and `help <option>' for info about that option.

!timeformat
set timeformat ks   show times in seconds, kiloseconds, etc.
set timeformat hms  use days, hours, minutes, seconds
