 ## `@endemolshinegroup/cosmiconfig-typescript-loader`
 
 This package serves as a drop in replacement for `@endemolshinegroup/cosmiconfig-typescript-loader`. At the time of publishing this, `endemolshinegroup` is not maintaining the original package. I can only assume this is to do with the fact that Endemol Shine Group [was purchased and absorbed by another business](https://en.wikipedia.org/wiki/Endemol_Shine_Group#Sale_to_Banijay). This discontinuation of development efforts towards the original package left any open issues and pull requests unresolved.
