Memoize::SDBM_File(3p)

NAME
Memoize::SDBM_File - DEPRECATED compability shim

DESCRIPTION
This class used to provide EXISTS support for SDBM_File before support for "EXISTS" was added to SDBM_File itself in Perl 5.6.0.

Any code still using this class should be rewritten to use SBDM_File directly.
