This manual describes version 8.1 of the CAT library. The
original specification for the library is described in the document The Starlink Subroutine Interface for Manipulating Catalogues
(StarBase/ACD/3.4)[2]. Version 8.1 of CAT is a
subset of this full implementation and some of the items present in it
serve no apparent purpose. These items correspond to features which were
in the original specification but which are not currently implemented.
These items may be implemented in future versions and have been included
so that applications written now will be compatible with future versions
of the library.
