147=item @check match expression
148
149Executes a match expression (see
150http://pod.tst.eu/http://cvs.schmorp.de/deliantra/server/lib/cf/match.pm)
151to see if it matches.
152
153C<self> is the npc object, C<object>, C<source> and C<originator> are the
154player communicating with the NPC.
155
156If the check fails, the match is skipped.
157
158=item @find match expression
159
160Like C<@check> in that it executes a match expression, but instead of
161failing, it gathers all objects matched into the C<@find> array variable.
162
163When you want to skip the match when no objects have been found, combine
164C<@find> with C<@cond>:
165
166 @match see my spellbook
167 @find type=SPELLBOOK in inv
