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.
