18# Bump ntp_configure_cache_version for each change to configure.ac or
19# .m4 files which invalidates cached values from previous configure
20# runs.
21#
22# If the change affects cache variables used only by the main NTP
23# configure.ac, then only its version number should be bumped, while
24# the subdir configure.ac version numbers should be unchanged.  The
25# same is true for a test/variable that is used only by one subdir
26# being changed incompatibly; only that subdir's cache version needs
27# bumping.
28#
29# If a change affects variables shared by all NTP configure scripts,
30# please bump the version numbers of each.  If you are not sure, the
31# safe choice is to bump all on any cache-invalidating change.
32#
33# In order to avoid the risk of version stamp collision between -stable
34# and -dev branches, do not simply increment the version, instead use
35# the date YYYYMMDD optionally with -HHMM if there is more than one
36# bump in a day.
