SCST administration utility
SCST administration utility scstadmin developed by Mark Buechler.
It can inspect and modify SCST through sysfs, either with individual commands or by applying a plain text configuration file.
Especially useful feature of scstadmin is ability to figure out and apply on the fly on the currently running system changes in scst.conf file. In other words, you can have SCST subsystem running with configuration from file scst.conf, then you edit this file, e.g. add new devices, then scstadmin will figure out that you added those devices and add them to SCST.
