source: trunk/gli/src/org/greenstone/gatherer/cdm/GeneralManager.java@ 6540

Last change on this file since 6540 was 6389, checked in by jmt12, 20 years ago

Introduced the idea of detail modes - these have an effect on several parts of the gui, such as disabling or hiding all regular expression based controls, simplifying the output from perl scripts and (having been given yet another new last minute feature to implement) displays a completely different create pane. Mode is stored in the config.xml and is changable via the Preferences controls
