This procedure queries the contents of the procedural database. It is supplied
with seven arguments matching procedures on { name, blurb, help, authors,
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.
