As the first line of output, print the approximate hit count.
As the last line of output, print the actual hit count.

=item --terse, -t

Do not print any URLs.
Only useful if you also specify --count.
If you specify --terse but not --count,
there will be no output no matter how many hits are found!

=item --all, -a

For each hit result, print all the URLs that the search engine
indicated were equivalent to it.  (Some URLs may refer to the same
object.)  Can be combined with --verbose; can not be combined with
--raw.

=item --raw, -r

For each hit result, print the raw HTML.
Not implemented for all backends.

=item --verbose, -v

Verbose mode.  Enumerate the returned URLs and show the description,
score, date, etc. for each.

=item --VERSION, -V

Print version information and exit immediately.

=item --debug <i>, -d <i>

Display back-end debugging information (with debug level <i>)

=item --host <hostname.sub.domain>

Set the _host option for the WWW::Search object (backend-dependent).

=item --port <i>

Set the _port option for the WWW::Search object (backend-dependent).

=item --username <bbunny>

Set the username with which to login to the backend.

=item --password <c4rr0t5>

Set the password with which to login to the backend.

=item --lwpdebug, -l

Display low-level libwww-perl debugging information
