I understand the motivation.  The version of logwatch has been historically
ancient in RHEL releases.

It may be not safe to assume that my current versions of postfix-logwatch will
just work in older versions of logwatch.  I'll make no guarantees there.  I've
also restructured the code into multiple perl modules, which will be shared with
amavis-logwatch, and future parsers.

One of the primary reasons I wrote postfix-logwatch, and added the standalone
feature, was so that the script could be run from the command line, allowing
more dynamic varieties of reports, which is not possible under logwatch without
modifying the conf/services/postfix.conf file before each run.  The standalone
config file is likely to be different than that used for logwatch (in
conf/services).  The newer --config_file option allows using varieties of
configuration files for specific reports, and command line options provide
further customization on the fly (esp. with new, upcoming features).

There is also a new man page; logwatch doesn't have module-specific man pages,
so this is a bit of a divergence.

As an "encouragement" to make the utility available in standalone mode, consider
speed and performance.  Logwatch is very clumsy and expensive in how it deals
with log files - it copies the primary log file, and when archives are being
searched, the archives as well, into a monolithic copy in the tmp directory. 
Performance on larger installations can be abysmal.  I encourage using
postfix-logwatch in standalone mode to avoid this excess.

I'd prefer not to deal with any confusions regarding which version filter is in
which version of logwatch.  If this can be minimized, I'm ok with it.
