There are three "system patterns" in use, which must be defined in the
startup section of the AIML files:

<aiml>
   <startup>
     <setup>
       <config name="connect-string"       value="CONNECT"/>
       <config name="infinite-loop-count"  value="128"/>
       <config name="infinite-loop-string" value="INFINITE LOOP"/>
       <config name="timeout-ms"           value="5000"/>
       <config name="timeout-string"       value="RESPONSE TIMEOUT"/>
     </setup>
     <bots>...</bots>
   </startup>
</aiml>

The template at <pat>CONNECT</pat> is used, if the user has no id - aka
first time connection - or if there is no user input. See
alice/extra.aiml shipped with ProgramV for an example.

The initialization of the user predicates is always done at a call to
the input handler with an existing user id and does not need to be
handled by a category. I think, this applies to all interpreters.

The interpreter must raise a fatal error at load time, if one of the
above patterns are missing.

A value of "0" for infinite-loop-count and timeout-ms mean, that those
cats will never be fired.

Maybe the botmaster should choose more "technical" patterns to avoid
interfering with normal patterns - aka "FN8 CONNECT 8NF", "INF99LOOP" or
  "666TIMEOUT666".
