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