=head1 OVERVIEW
The clipboard can store an unlimited number of copies of
-Rose::DB::Object instance. The instances are dumped into trees using
+Rose::DB::Object instances. The instances are dumped into trees using
L<Rose::DB::Object::Helpers/as_tree>. How much of such an object is
copied depends on its type. For example, a dump of a customer object
might also include the dumps of the shipping address and contact
C<SL::Clipboard::RequirementSpecItem>. These support classes must
inherit from L<SL::Clipboard::Base> which offers almost a full set of
support functions so that the actual specialized class has to do very
-litte.
+little.
As the clipboard is session-based its contents will be lost when the
session expires (either due to timeouts or to the user logging off).
=item C<copy $object>
Creates a dumped copy of C<$object> and stores that copy in the
-session. An unlimited number of copies of differeing types can be
+session. An unlimited number of copies of differing types can be
made.
Returns the instance of the copied object, a sub-class of
=item C<get_entry [$type]>
Returns the most recently clipped object whose type matches the
-regular expression C<$type>. If C<$type> is not given then then then
+regular expression C<$type>. If C<$type> is not given then the
most recently copied object is returned.
If no such object exists C<undef> is returned instead.
