CentOS 7.0 - man page for lwp::mediatypes (centos section 3)

LWP::MediaTypes(3)	       User Contributed Perl Documentation	       LWP::MediaTypes(3)

       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 'Content-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:
