-=head1 NAME
-
-mimetype - Determine file type
-
-=head1 SYNOPSIS
-
-mimetype [options] [-] files
-
-=head1 DESCRIPTION
-
-This script tries to determine the mime type of a file using the
-Shared MIME-info database. It is intended as a kind of I<file(1)> work-alike,
-but uses mimetypes instead of descriptions.
-
-If one symlinks the I<file> command to I<mimetype> it will behave
-a little more compatible, see L</--file-compat>.
-Commandline options to specify alternative magic files are not
-implemented the same because of the conflicting data formats.
-Also the wording of the descriptions will differ.
-
-For naming switches I followed the manpage of file(1) version 4.02
-when possible. They seem to differ completely from the spec in the
-'utilities' chapter of IEEE Std 1003.1-2001 (POSIX).
-
-=head1 OPTIONS
-
-=over 4
-
-=item B<-a>, B<--all>
-
-Show output of all rules that match the file.
-
-TODO: this method now just returns one match for each
-method (globs, magic, etc.).
-
-=item B<-b>, B<--brief>
-
-Do not prepend filenames to output lines (brief mode).
-
-=item B<--database>=I<mimedir>:I<mimedir>:...
-
-Force the program to look in these directories for the shared mime-info
-database. The directories specified by the basedir specification
-are ignored.
-
-=item B<-d>, B<--describe>
-
-Print file descriptions instead of mime types, this is the
-default when using L</--file-compat>.
-
-=item B<-D>, B<--debug>
-
-Print debug information about how the mimetype was determined.
-
-=item B<-f> I<namefile>, B<--namefile>=I<namefile>
-
-Read the names of the files to be examined from the file 'namefile'
-(one per line) before the argument list.
-
-=item B<--file-compat>
-
-Make mimetype behave a little more L<file(1)> compatible. This
-is turned on automaticly when you call mimetype by a link
-called 'file'.
-
-A single '-' won't be considered a seperator
-between options and filenames anymore, but becomes identical to L</--stdin>.
-( You can still use '--' as seperator, but
-that is not backward compatible with the original file command. )
-Also the default becomes to print descriptions instead of mimetypes.
-
-=item B<-F> I<string>, B<--separator>=I<string>
-
-Use string as custom separator between the file name and its mimetype
-or description, defaults to ':' .
-
-=item B<-h>, B<--help>
-
-=item B<-u>, B<--usage>
-
-Print a help message and exits.
-
-=item B<-i>, B<--mimetype>
-
-Use mime types, opposite to L</--describe>,
-this is the default when _not_ using L</--file-compat>.
-
-=item B<-L>, B<--dereference>
-
-Follow symbolic links.
-
-=item B<-l> I<code>, B<--language>=I<code>
-
-The language attribute specifies a two letter language code, this makes
-descriptions being outputted in the specified language.
-
-=item B<-M>, B<--magic-only>
-
-Do not check for extensions, globs or inode type, only look at the content
-of the file. This is particularly useful if for some reason you don't trust
-the name or the extension a file has.
-
-=item B<-N>, B<--noalign>
-
-Do not align output fields.
-
-=item B<--output-format>
-
-If you want an alternative output format, you can specify a format string
-containing the following escapes:
-
- %f for the filename
- %d description
- %m mime type
-
-Alignment is not available when using this,
-you need to post-process the output to do that.
-
-=item B<--stdin>
-
-Determine type of content from STDIN, less powerfull then normal file checking
-because it only uses magic typing. This will happen also if the STDIN filehandle
-is a pipe.
-
-To use this option L<IO::Scalar> needs to be installed.
-
-=item B<-v>, B<--version>
-
-Print the version of the program and exit.

-
-=head1 ENVIRONMENT
-
-=over 4
-
-=item XDG_DATA_HOME
-
-=item XDG_DATA_DIRS
-
-These variables can list base directories to search for data files. The shared
-mime-info will be expected in the "mime" sub directory of one of these
-directories. If these are not set, there will be searched for the
-following directories:
-
- $HOME/.local/share/mime
- /usr/local/share/mime
- /usr/share/mime
-
-See also the "XDG Base Directory Specification"
-L<http://freedesktop.org/Standards/basedir-spec>
-
-=back
-
-=head1 FILES
-
-The base dir for all data files is determined by two environment variables,
-see L</ENVIRONMENT>.
-
-=over 4
-
-=item F<BASE/mime/packages/SOURCE.xml>
-
-All other files are compiled from these source files. To re-compile them
-use B<update-mime-database(1)>.
-
-=item F<BASE/mime/globs>
-
-Compiled information about globs.
-
-=item F<BASE/mime/magic>
-
-Compiled information about magic numbers.
-
-=item F<BASE/mime/MEDIA/SUBTYPE.xml>
-
-Descriptions of a mimetype in multiple languages, used for the
-L</--describe> switch.
-
-=back
-
-=head1 DIAGNOSTICS
-
-If a file has an empty mimetype or an empty description,
-most probably the file doesn't exist and the given name
-doesn't match any globs. An empty description can also mean that
-there is no description available in the language you specified.
-
-The program exits with a non-zero exit value if either the commandline
-arguments failed, a module it depends on wasn't found or the shared
-mime-info database wasn't accesable. See L<File::MimeInfo> for more details.
-
-=head1 TODO
-
-The '--all' switch doesn't really show all matches, but only one per
-mime-typing method. This needs to be implemnted in the modules first.
-
-=head1 BUGS
-
-No known bugs, please mail the author if you find one.
-
-B<mimetype> doesn't provide a switch for looking inside compressed files
-because it seems to me that this can only be done by un-compressing the file,
-something that defeats the purpose. On the other hand the option should
-exist for strict compatibility with file(1). Possibly a subclass should be
-made for this one day.
