List of standard media types and their usual file extension
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).
