# Notes on generating releases:
# (1) update NEWS
# (2) update CHANGELOG -- put in release number
# (3) update release number in configure.in and smartmontools.spec
# (4) update internal changelog in smartmontools.spec
# (5) to test, set USECVS below to 0
# (6) when satisfied, set USECVS below to 1
