0.05 -- 
	- Modularize most functions
	- Change <BackupDirectory ...> to <Directory ...>
	- Enhance charge file to add total size, xfer rate, etc.
	- regularize logging/debug

0.07 --
	- Allow use of rsync urls, i.e. system::tag/dir, to back up
	- Fix status code display

0.08 --
	- Add snapcopy command to allow efficient copy.
	- snapcopy includes POD docs.
	- Add Before and After directives to constrain backup to
	  certain times.
	- Add IgnoreVanished directive to ignore the "file has vanished"
	  error from rsync which causes most of the error emails. This
	  typically happens when a PID or other transient file goes
	  away.

0.09 --
	- Repeat to yourself -- proper testing includes a try at
	  "make install".

0.11 --
    - Add PingCommand directive that specifies command to run
	  to check connection to target system before backup.
	- Use help from David Stoergel <lorax_at_lorax_dot_org>
	  to finish IgnoreVanished.

0.12 --
    - Add Timestamp to debug output
    - Matthias Pfafferodt contributed change to weekly/monthly backup so
      it is done if more than 7 days or 30 days have elapsed. Before, it
      would not work unless it was run on first day of week or month,
      and that could cause a problem when the target system was down on
      that day. Thanks to Matthias (Matthias.Pfafferodt at the excellent
      domain mapfa.de).

0.912 --
    - Silly me, ran afoul of CPAN's numbering restrictions.

0.913 --
    - Didn't know they checked contained modules too, sigh.
