+A special function provided here is E<db>. Without it you'd have to write:

+  my $part = SL::DB::Part->new(id => 1234);
+  my @all_parts = SL::DB::Manager::Part->get_all;
+
+with them it becomes:

+  my @all_parts = db('parts')->get_all;
+
+You don't have to care about add that SL::DB:: incantation anymore. Also, a
+simple s at the end will get you the associated Manager class.
+
+db is written to try to make sense of what you give it, but if all fails, it
