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. | |
