+=head1 NAME
+
+Rose::DBx::Cache::Anywhere - get Apache::DBI behaviour without Apache
+
+=head1 DESCRIPTION
+
+This class is used by Rose::DBx::AutoReconnect.
+The author uses
+Rose::DB with Catalyst under both the Catalyst dev server and
+FastCGI and found that the standard Rose::DB::Cache behaviour
+did not work well with those environments.
+
+=head1 METHODS
+
+=head2 prepare_db( I<rose_db>, I<entry> )
+
+Overrides default method to always ping() dbh if not running
+under mod_perl.
