How to sing "99-bottles of beer" with EPICS:
- download and compile an ioc-shell with the SynApps package
- load the above database to this ioc-shell
- monitor the stringin PV "printer"
- write the desired number of bottles (99) to the PV "bottlecount"
Each line of the song is written in a timed sequence to the "printer".
