dnl Advanced information about versioning:
dnl * "Writing shared libraries" by Mike Hearn
dnl http://plan99.net/~mike/writing-shared-libraries.html
dnl * libtool.info chapter "Versioning"
dnl * libtool.info chapter "Updating library version information"
dnl ---------------------------------------------------------------------------
dnl Versioning:
dnl - CURRENT (Major): Increment if the interface has changes. AGE is always
dnl *changed* at the same time.
dnl - AGE (Micro): Increment if any interfaces have been added; set to 0
dnl if any interfaces have been removed. Removal has
dnl precedence over adding, so set to 0 if both happened.
dnl It denotes upward compatibility.
dnl - REVISION (Minor): Increment any time the source changes; set to
dnl 0 if you incremented CURRENT.
dnl
dnl To summarize. Any interface *change* increment CURRENT. If that interface
dnl change does not break upward compatibility (ie it is an addition),
dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed,
dnl REVISION is set to 0, otherwise REVISION is incremented.
