dnl How to update library version number
dnl ====================================
dnl
dnl Update the version information only immediately before a public
dnl release of the software. More frequent updates are unnecessary.
dnl
dnl CURRENT: increment if the interface has additions, changes, removals.
dnl
dnl REVISION: increment any time the source changes; set to 0 if you
dnl incremented CURRENT
dnl
dnl AGE: increment if any interfaces have been added; set to 0 if any
dnl interfaces have been removed. removal has precedence over adding,
dnl so set to 0 if both happened.
