[otrs] Loading settings for SysConfig via file ...

Could someone please point me to more detailed information about the load settings facility on the sysconfig page? I've scanned through the documentation, and although this is mentioned it is not explained enough so that I can understand it. This is handy for a customer specific package of settings that needs to take effect within OTRS, more specifically via calls to $Self->{ConfigObject}->Get('Module::Name::Thing'), etc. How does one get this to appear somewhere in the sysconfig page so that the customer can later edit it to fit his/her specific requirements.
