Changes since 1.0.14:
* When running without the --lowmem or --verylowmem options,
  Tarsnap conserves memory if it encounters lots of small files;
  at worst, Tarsnap's memory consumption is roughly double the
  memory which would be consumed if the --lowmem option were
  specified.
* Add --dry-run option to tarsnap -c which simulates storing an
  archive without actually sending anything over the network.
* The tarsnap.1 and tarsnap.conf.5 manual pages now reference the
  correct default configuration file location if the CONFIGDIR
  variable (on FreeBSD) or the sysconfdir variable (with autoconf)
  is not /usr/local/etc.
* The autoconf build code no longer passes -Werror to the
  compiler; this allows tarsnap to build with gcc 4.3.
