Check if mod exists / is enabled

[Glockshna]

Is there a way to do as the title says? Working on a mod that adjusts balance and attributes of many other mods but don't want to have to set 500 dependencies and config options to enable and disable changes to each mod based on what is installed.

Thanks.
