additional magic files
----------------------

How users can inject their own magics for fun:

  1. open /etc/magic and /etc/magic.mime with a text editor, as root,
     and add your own magics.

  2. have fun.


How package maintainers can inject their own magics for profit:

  1. place your magics as plain text files in
     /usr/share/file/${binary_package_name}.

  2. call 'file --compile ${binary_package_name}' from /usr/share/file
     in your postinst script (maybe we should have a trigger for that
     at some point). this will produce the binary magics
     /usr/share/file/${binary_package_name}.mgc.

  3. remove the binary magics in your postrm script.

  4. profit.


seccomp support
---------------

Starting with version 1:5.37-1, file is built using libseccomp. This
will introduce a regression if applications call the program with the
--uncompress option, and file(1) needs the help of external programs
for uncompression.
