 =item $who - The cf::object::player object that initiated the dialogue.
 =item $npc - The NPC (or magic_ear etc.) object that is being talked to.
+=item $map - The map the NPC (not the player) is on.
 =item $msg - The actual message as passed to this method.
 =item $match - An arrayref with previous results from C<@parse>.
 =item $state - A hashref that stores state variables associated
 =item $flag - A hashref that stores flags associated with the player and
 can be seen by all NPCs (so better name your flags uniquely). This is
 useful for storing e.g. quest information. See C<@setflag> and C<@ifflag>.
+=item $find - see @find, below.
 =back
 The environment is that standard "map scripting environment", which is
 limited in the type of constructs allowed (no loops, for example).
 Like C<@cond>, but proceed regardless of the outcome.
 =item @msg perl
 Like C<@cond>, but the return value will be stringified and prepended to
-the message.
+the reply message.
+=item @check match expression
+Executes a match expression (see
+http://pod.tst.eu/http://cvs.schmorp.de/deliantra/server/lib/cf/match.pm)
+to see if it matches.
+C<self> is the npc object, C<object>, C<source> and C<originator> are the
+player communicating with the NPC.
+If the check fails, the match is skipped.
+=item @find match expression
+Like C<@check> in that it executes a match expression, but instead of
+failing, it gathers all objects into an array and provides a reference to
+the array in the C<$find> variable.
+When you want to skip the match when no objects have been found, combine
+C<@find> with C<@cond>:
+   @match see my spellbook
+   @find type=SPELLBOOK in inv
+   @cond @$find
+   It looks dirty.
+   @match see my spellbook
+   I can't see any, where do you have it?
 =item @setstate state value
 Sets the named state C<state> to the given C<value>. State values are
 associated with a specific player-NPC pair, so each NPC has its own state
 See C<@ifstate> for an example.
 =item @ifstate state value
 Requires that the named C<state> has the given C<value>, otherwise this
-topic is skipped.  For more complex comparisons, see C<@cond> with
+topic is skipped. For more complex comparisons, see C<@cond> with
 C<$state>. Example:
   @match quest
   @setstate question quest
   Do you really want to help find the magic amulet of Beeblebrox?
 associated with a specific player and can be seen by all NPCs. with
 respect to a particular player, which makes them suitable to store quest
 markers and other information (e.g. reputation/alignment). Flags are
 persistent over the lifetime of a player, so be careful :)
+Perversely enough, using C<@setfflag> without a C<value> clears the flag
+as if it was never set, so always provide a flag value (e.g. C<1>) when
+you want to set the flag.
 See C<@ifflag> for an example.
 =item @ifflag flag value
 Requires that the named C<flag> has the given C<value>, otherwise this
-topic is skipped.  For more complex comparisons, see C<@cond> with
+topic is skipped. For more complex comparisons, see C<@cond> with
-C<$flag>. Example:
+C<$flag>.
+If no C<value> is given, then the ifflag succeeds when the flag is true.
+Example:
   @match I want to do the quest!
   @setflag kings_quest 1
   Then seek out Bumblebee in Navar, he will tell you...
   @match I did the quest
 When the state argument is omitted the trigger is stateful and retains an
 internal state per connected-id. There is a limitation to the use of this: The
 state won't be changed when the connection is triggered by other triggers.  So
 be careful when triggering the connection from other objects.
-When a state argument is given it should be either 0 or 1. 1 will 'push' the connection
+When a state argument is given it should be a positive integer. Any value
-and 0 will 'release' the connection. This is useful for example when you want to
+C<!= 0> will 'push' the connection (in general, you should specify C<1>
-let a npc control a door.
+for this) and C<0> will 'release' the connection. This is useful for
+example when you want to let an NPC control a door.
 Trigger all objects with the given connected-id by 'releasing' the connection.
