dnl 1. If you have changed any of the sources for this library, the revision
dnl number must be incremented. This is a new revision of the current
dnl interface.
dnl 2. If the interface has changed, then current must be incremented, and
dnl revision reset to `0'. This is the first revision of a new interface.
dnl 3. If the new interface is a superset of the previous interface (that is,
dnl if the previous interface has not been broken by the changes in this new
dnl release), then age must be incremented. This release is backwards
dnl compatible with the previous release.
dnl 4. If the new interface has removed elements with respect to the previous
dnl interface, then you have broken backward compatibility and age must be
dnl reset to `0'. This release has a new, but backwards incompatible
dnl interface.
