1# Base source of start-up shell script for the Exim Monitor. Used to set the
2# required environment variables before running the program. Using script
3# rather than a configuration file means that computation can be done.
4# The build process concatenates on the front of this various settings from
5# os-specific files and from the user's configuration file.
