2050276Speter# If the change affects cache variables used only by the main NTP
2150276Speter# configure.ac, then only its version number should be bumped, while
2250276Speter# the subdir configure.ac version numbers should be unchanged.  The
2350276Speter# same is true for a test/variable that is used only by one subdir
2450276Speter# being changed incompatibly; only that subdir's cache version needs
2550276Speter# bumping.

2750276Speter# If a change affects variables shared by all NTP configure scripts,
2850276Speter# please bump the version numbers of each.  If you are not sure, the
2950276Speter# safe choice is to bump all on any cache-invalidating change.
