Development menu contains a number of options for the developers of CASCADE and for users of experimental components not yet ready for general use. As of this writing, there are four items under this menu choice. ``editres'' is a program that allows you to take a snapshot of a running X Window System program, and show all of the objects that are active and their properties (figure 30). ``POSIX'' contains some linking and reporting tools under development in response to the requests of a group working on the posix standard. ``Xterm'' provides xterm window session. ``SGML'' options are prototype procedures for pruning and grafting branches of SGML trees to edit them in a way that allows element or subdocument locking. Finally, the ``Administrative Stuff'' option is designed to allow the developers to upgrade file formats for record files on the fly.
