media-types - 4.0.0 main

This package installs the configuration file /etc/mime.types, that lists
standard media types (originally known as "MIME" types) and their usual file
extension. This provides a simple way for programs to have a first guess at a
file's content. On standard Debian desktop systems, one will also find more
sophisticated tools, for instance provided by the "file" and "xdg-utils"
packages.
.
The /etc/mime.types file is compiled by hand using mostly information provided
by the Internet Assigned Numbers Authority (IANA).
