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.
