The real question is why write such a module when there are tons of them?

 A valid question; basically because this is a perl re-implementation of some C code. The config file parser has to be 100% compatible with the old codes behaviour.

 Also it should be possible for the settings in the configuration file to be overridden by the contents of environmental variables, which no existing code I saw supported.

 (The environmental variable overrides is necessary for my testing scripts/testing system - fully automatic regression testing of the project as a whole, and the modules it is implmented via/with).
