Here's a diff against 2007-01-08 snapshot that adds an optional 'regexp_match'
argument to the receive command which allows regexp style patterns to be
supplied for matching.
This allows a scenario to act as a 'universal' catcher. Meaning it can receive
multiple message types and respond to them all with the same 200 OK.
Particularly for presence testing, this would be useful for simulating a UAS
that OKs incoming publishes, subscribes, and IMs.
Example:
<recv request="MESSAGE|PUBLISH|SUBSCRIBE" crlf="true" regexp_match="true">
</recv>
If regexp_match is not supplied, the old behavior persists.
