+=head1 NAME
+
+DBI::Util::CacheMemory - a very fast but very minimal subset of Cache::Memory
+
+=head1 DESCRIPTION
+
+Like Cache::Memory (part of the Cache distribution) but doesn't support any fancy features.
+
+This module aims to be a very fast compatible strict sub-set for simple cases,
+such as basic client-side caching for DBD::Gofer.
+
+Like Cache::Memory, and other caches in the Cache and Cache::Cache
+distributions, the data will remain in the cache until cleared, it expires,
+or the process dies. The cache object simply going out of scope will I<not>
+destroy the data.
+
+=head1 METHODS WITH CHANGES
+
+=head2 new
+
+All options except C<namespace> are ignored.
+
+=head2 set
+
+Doesn't support expiry.
+
+=head2 purge
+
+Same as clear() - deletes everything in the namespace.
+
