+// This file wraps the logic of go-enry (https://github.com/go-enry/go-enry) to support additional languages.
+// go-enry is based off of a package called Linguist (https://github.com/github/linguist)
+// and sometimes programming languages may not be supported by Linguist
+// or may take a while to get merged in and make it into go-enry. This wrapper
+// gives us flexibility to support languages in those cases. We list additional languages
+// in this file and remove them once they make it into Linguist and go-enry
