Mimetype Functions
Mimetype
&reftitle.intro;
The functions in this module try to guess the content type
and encoding of a file by looking for certain
magic byte sequences at specific
positions within the file. While this is not a bullet proof
approach the heuristics used do a very good job.
This extension is derivated from Apache mod_mime_magic,
which is itself based on the file
command maintaind by Ian F. Darwin. See the source code for
further historic and copyright information.
&reftitle.required;
&no.requirement;
&reftitle.install;
The extension needs a copy of the magic.mime
as distributed with the file command.
This file also part of most recent Linux distributions and usually
stored in the /usr/share/misc directory.
