This software package can be used to convert virtually any mail reading program into a multimedia mail reading program. The implementation is extremely flexible and extensible, using a .mailcap file mechanism for support of new data formats. Programs like exmh use metamail to help display messages with MIME content. This makes sending MIME content and external references very simple.
MIME content includes audio, video, and pictures loaded from files or as the output of commands.
