Still ironing out the rough edges of the new major release, 2.1.2 fixes
rsync options generations. Upgrade from 2.1.0 or 2.1.1 strongly
recommended, 2.0.7 is okay if you stay with the old format.
fix: added excludeFrom to checkgauge (thx to DavidWittman)
fix: fixed rsync option computation
enhancement: added password_file file option to rsync
