"Best OPI Yet" (BOY) is an operator display builder created at Oak Ridge National Laboratory as part of the Control System Studio (CSS). A number of the MEDM display files for area detector have been ported over, in part as an evaliation of BOY.
The package provided (source files located in ADApp/CSS-BOY) consist of an Eclipse plugin named "gov.anl.aps.synApps.areaDetector". The plugin itself contains a number of the base level screens intended to be used as templates combined with implementation specific instances, much like the MEDM screens provided.
To use these screens, the plugin will be installed into the plugins directory in CSS. Since Oak Ridge and DESY each have separate CSS implementations with different operator interface programs, it is recommended that novice users download the latest version from Oak Ridge.
