#
# Note about the pattern for release iterations (ie. the release value of
# name-version-release):
#     If you are still in development, but the production package is expected
#     to have a release value of 8 (previous release was 7) for example, you
#     always work one step back (in the 7's) and add another significant digit.
#     I.e., release value of 7.1, 7.2, 7.3, etc... are all pre-production
#     release nomenclatures for an eventual release numbered at 8. When we go
#     into production, we "round up" and drop the decimal and probably all the
#     snapinfo as well.  specpattern-1.0.1-7.3.beta2 --> specpattern-1.0.1-8

%description
rtb (leveraging rsync-time-backup and its rtb-wrapper extension) is a
time-machine-like backup utility. It leverages rsync to create incremental
backups managed using hardlinks between backup trees.  It has many similarities
in concept to backintime, but is focused on simplicity.  Profiles can be
defined for different backup scenarios.
