As always, I'm open to any feature requests and bug reports.

The changelist from the previous announced release is as follows:

Changes for 20070915:

* Added 'grok_patfind.pl' which adds 'grok -F' functionality. Read
about it
here:

* Proper shutdown is called to kill the "hack" subprocess
* Add 'shell' option to 'type' sections; not currently used.
* Warn if we're trying to override an existing filter.
* Added more perlthoughts to t/theory/

* Numerous pattern regex changes:
- NUMBER no longer uses Regexp::Common's real number regex since
that one
matches '.' and my thoughts are that '.' is not a number
- Added POSITIVENUM pattern
- Fix HOSTNAME to match hostnames starting with a number (Again,
Regexp::Common fails me)
- Add path patterns: UNIXPATH, WINPATH, URI
- MONTH no longer matches 0 through 12
- DAY no longer matches 0 through 6
- SYSLOGPROG is more specific now, since valid prog names can have
dashes.
