+=head1 NAME
+
+SL::MoreCommon.pm - helper functions
+
+=head1 DESCRIPTION
+
+this is a collection of helper functions used in Lx-Office.
+Most of them are either obvious or too obscure to care about unless you really have to.
+The exceptions are documented here.
+
+=head2 FUNCTIONS
+
+=over 4
+
+=item save_form
+=item restore_form
+
+A lot of the old sql-ledger routines are strictly procedural. They search for params in the $form object, do stuff with it, and return a status code.
+
+Once in a while you'll want something from such a function without altering $form. Yeah, you could rewrite the routine from scratch... not. Just save you form, execute the routine, grab your results, and restore the previous form while you curse at the original design.
