Summary
• CSS = Control System Apps as Eclipse Plugins
• Not all pieces work everywhere or are production-ready
– But some are better than previous EPICS GUI tools
– You pick what you want, or add your own
• Good for end user
– Homogeneous “Product”, common preferences,
online help, data exchange between applications
