Short description of Evidence control system

This directory contains the backbone of the control system.

Config is the configuration server and needs to run before any other DIM
server that requests configuration information is started (if a configuration
request cannot be answered, a server will normally not start). As default,
it reads Evidence.conf in the config subdirectory. A different configuration
file can be given on the command line.

DColl is the central data collector. It subscribes to all services handled by
the name server and writes them to disk (except those excluded in the
configuration file). It also provides a history service for all DIM services
and a command for logging.

Alarm can be configured to check all servers for availability and status and
can produce a master alarm.

The DIMDIR environment variable needs to point to the DIM installation directory
when compiling. DIM_DNS_NODE must point to a name server for any DIM server
to run.
