Queries the procedural database for its contents using regular
expression matching.
</p>
<p>
This procedure queries the contents of the procedural database. It
is supplied with seven arguments matching procedures on { name,
blurb, help, author, copyright, date, procedure type}. This is
accomplished using regular expression matching. For instance, to
find all procedures with \"jpeg\" listed in the blurb, all seven
arguments can be supplied as \".*\", except for the second, which
can be supplied as \".*jpeg.*\". There are two return arguments for
this procedure. The first is the number of procedures matching the
query. The second is a concatenated list of procedure names
corresponding to those matching the query. If no matching entries
are found, then the returned string is NULL and the number of
entries is 0.
