Version 12/01: First release. Version 02/02: Second release. Changes as follows: SEGMAN:segman;load-system.lisp now includes the DEVELOPMENT subsystem containing a graphical application for specifying pixel patterns. SEGMAN:development;capture-application.lisp (new) contains the application's window definition. SEGMAN:development;capture.lisp (new) contains the application's general interaction functionality. SEGMAN:segman;debugging.lisp (new) contains definitions from elsewhere, including *verbose*, *verbose-indentation-level*, verbose-message, and with-verbosity. These are not significant, but were moved to avoid compilation warnings. There is a new function as well, describe-group. SEGMAN:segman;pattern.lisp (old) contains a new function, groups-at-position, which is needed for the application. SEGMAN:segman;packages.lisp adds "GROUPS-AT-POSITION" and "GROUP-UNDER-CURSOR" to the exported list. It should also include "*ALL-GROUPS*" but I think I missed that.
