dnl (*) There was an error on this release.  Firstly, the versioning
dnl numbers were not updated.  Secondly, 2 functions were removed, but
dnl the age not reset--this should have been 11:0:0.  However these
dnl functions were not documented and are regarded as internal, so we
dnl will assume 11:0:11.

dnl How to update library version number
dnl ====================================
dnl 
dnl C: increment if the interface has additions, changes, removals.
dnl
dnl R: increment any time the source changes; set to 0 if you
dnl incremented CURRENT
dnl
dnl A: 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.
