       LWP::MediaTypes - guess media type for a file or a URL

        use LWP::MediaTypes qw(guess_media_type);
        $type = guess_media_type("/tmp/foo.gif");

       This module provides functions for handling media (also known as MIME) types and encodings.  The mapping from
       file extensions to media types is defined by the media.types file.  If the ~/.media.types file exists it is
       used instead.  For backwards compatibility we will also look for ~/.mime.types.

       The following functions are exported by default:

       guess_media_type( $filename )
       guess_media_type( $uri )
       guess_media_type( $filename_or_uri, $header_to_modify )
           This function tries to guess media type and encoding for a file or a URI.  It returns the content type,
           which is a string like "text/html".  In array context it also returns any content encodings applied (in the
           order used to encode the file).  You can pass a URI object reference, instead of the file name.

           If the type can not be deduced from looking at the file name, then guess_media_type() will let the "-T"
           Perl operator take a look.  If this works (and "-T" returns a TRUE value) then we return text/plain as the
           type, otherwise we return application/octet-stream as the type.

           The optional second argument should be a reference to a HTTP::Headers object or any object that implements
           the $obj->header method in a similar way.  When it is present the values of the 'Content-Type' and 'Con-
           tent-Encoding' will be set for this header.

       media_suffix( $type, ... )
           This function will return all suffixes that can be used to denote the specified media type(s).  Wildcard
           types can be used.  In a scalar context it will return the first suffix found. Examples:

             @suffixes = media_suffix('image/*', 'audio/basic');
             $suffix = media_suffix('text/html');

       The following functions are only exported by explicit request:

       add_type( $type, @exts )
           Associate a list of file extensions with the given media type.  Example:

               add_type("x-world/x-vrml" => qw(wrl vrml));

       add_encoding( $type, @ext )
           Associate a list of file extensions with an encoding type.  Example:

            add_encoding("x-gzip" => "gz");

       read_media_types( @files )
           Parse media types files and add the type mappings found there.  Example:
