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.

!who
who [<nick>]
 Gives information about who I think the nick is (or who I think you
 are), including whether the nick is registered, whether it is
 associated with a username and if so who, and whether the current
 user of the nick has identified themselves to me.

!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)
(Not yet implemented.)

!op
op             on channel
op <channel>   (privately)
 I'll give you channel operator privilege, if you're a manager.

!channel
channel [<chan>] [show]                     show settings
channel [<chan>] manager +|-|= <nick> ...   set manager list
channel [<chan>] autojoin yes|no            join at bot start ?
 See `help <setting>' (eg, `help manager') for more info.

!autojoin
channel [<chan>] autojoin yes|no      (`yes' is default.)
 Controls whether I'll join the channel when I'm (re)started.
(Not yet implemented.)

!manager
channel [<chan>] manager + <nick> <nick> ...  add managers
channel [<chan>] manager - <nick> <nick> ...  remove managers
channel [<chan>] manager = <nick> <nick> ...  set new manager list
 Managers are those who can use the `channel' command to change
 channel settings.  Manager status is only effective for secure
 nicks, after the manager has identified themselves.
 If you op me on an unmanaged channel you become the only manager,
 but you must use `channel' to change a channel setting to make this
 permanent.  To make a channel unmanaged, make it have no managers.

!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'.)

!blight-id
/blight-id is a command available in ircII (and possibly other
clients) on chiark.  It sets up a password if you don't already have
one, and then uses it to identify you to Blight.  If you want to
change your password, delete the file ~/.userv/irc-pass-md5.

!identpass
identpass <username> <password>
 Identifies you to Blight.  To set up your password, or be reminded
 of it, run the shell command `irc-blight-id' on chiark.
 (On ircII on chiark `/blight-id' is easier, see `help blight-id'.)
 See `help identpass-internals' for technical details.

!identpass-internals
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.
By default this checks the md5sum against ~/.userv/irc-pass-md5.

!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
