 - [ ] aiml: scripts to vary parameters
 - [ ] base: scripts to perform basic operation and talk to devices (stepper motors, camera, power supply). Currenly, the protocop use are EPICS (when available) and TCP (for AWA legacy system)
+- [ ] ESSPSCtrl: control for ESS power supply (currently 12/09 conencted to JLab coil)
 - [ ] camera: scripts to acquire data from CCD camera (example from the NI frame grabber, and Point Grey camera). Not the radCAM need further work.
 - [ ] laser:  scripts to controls laser devices (e.g. alpha-BBO Xtal, and lambda/2 polarizer)
 - [ ] legacy_scripts: old scripts based on the legacy AWA control system
