Lightweight File 'MIME' Type Detection Based On Contents or Extension
## Description
'MIME' types are shorthand descriptors for file contents and can be
determined from "magic" bytes in file headers, file contents or intuited from file extensions. Tools are provided to perform curated "magic" tests as well as mapping 'MIME' types from a database of over 1,500 extension mappings.
