-# information:
-#
-#   If there is any interface change, increment CURRENT (major).  If that
-#   interface change does not break upward compatibility (i.e. it is an
-#   addition), increment AGE (micro), Otherwise AGE is reset to 0. If CURRENT
-#   has changed, REVISION (minor) is set to 0, otherwise REVISION is
-#   incremented.

+# Versions are denoted using a standard triplet of integers:
+# MAJOR.MINOR.PATCH. The basic intent is that MAJOR versions are
+# incompatible, large-scale upgrades of the API. MINOR versions retain
+# source and binary compatibility with older minor versions, and changes
+# in the PATCH level are perfectly compatible, forwards and backwards.
+# See http://apr.apache.org/versioning.html.
