This library contains a database of MIME types that maps filename extensions
into MIME types suitable for use in many Internet protocols such as HTTP or
e-mail. It is generated from the mime.types file found in Unix systems, but
has no dependency on a filesystem since it includes the contents of the
database as an ML datastructure.
For example, here's how to lookup MIME types in the [utop] REPL:
#require "magic-mime";;
Magic_mime.lookup "/foo/bar.txt";;
- : bytes = "text/plain"
Magic_mime.lookup "bar.css";;
- : bytes = "text/css"
