NAME
       MIME::Types - Definition of MIME types
INHERITANCE
        MIME::Types
          is a Exporter
SYNOPSIS
        use MIME::Types;
        my $mimetypes = MIME::Types->new;
        my MIME::Type $def = $mimetypes->type('text/plain');
        my MIME::Type $def = $mimetypes->mimeTypeOf('gif');
DESCRIPTION
       MIME types are used in MIME compliant lines, for instance as part of
       e-mail and HTTP traffic, to indicate the type of content which is
       transmitted.  Sometimes real knowledge about a mime-type is need.
       This module maintains a set of MIME::Type objects, which each describe
       one known mime type.  There are many types defined by RFCs and vendors,
       so the list is long but not complete.  Please don't hestitate to ask to
       add additional information.
       If you wish to get access to the "mime.types" files, which are
       available on various places in UNIX and Linux systems, then have a look
       at File::TypeInfo.
   MIME::Types and mod_perl
       This module uses a DATA handle to read all the types at first
       instantiation, which doesn't play nicely with mod_perl and fork.
       When you use this module with mod_perl, add this to "startup.pl"
          use MIME::Types;
          BEGIN { MIME::Types->new() }
       Now, the type definitions will get parsed before the processes are
       spawned.
   MIME::Types and daemons (fork)
       If your program uses fork (usually for a daemon), then the situation is
       a bit like with mod_perl before: you want to have the type table
       initialized before you start forking. So, first call
          my $mt = MIME::Types->new;
       Later, each time you create this object (you may, of course, also reuse
       the object you create here) you will get access to the same global
       table of types.
METHODS
   Instantiation
       MIME::Types->new(OPTIONS)
           Create a new "MIME::Types" object which manages the data.  In the
           current implementation, it does not matter whether you create this
           object often within your program, but in the future this may
           change.
            -Option       --Default
             only_complete  <false>
           only_complete => BOOLEAN
             Only include complete MIME type definitions: requires at least
             one known extension.  This will reduce the number of entries
             --and with that the amount of memory consumed-- considerably.
             In your program you have to decide: the first time that you call
             the creator ("new") determines whether you get the full or the
             partial information.
   Knowledge
       $obj->addType(TYPE, ...)
           Add one or more TYPEs to the set of known types.  Each TYPE is a
           "MIME::Type" which must be experimental: either the main-type or
           the sub-type must start with "x-".
           Please inform the maintainer of this module when registered types
           are missing.  Before version MIME::Types version 1.14, a warning
           was produced when an unknown IANA type was added.  This has been
           removed, because some people need that to get their application to
           work locally... broken applications...
       $obj->extensions()
           Returns a list of all defined extensions.
       $obj->mimeTypeOf(FILENAME)
           Returns the "MIME::Type" object which belongs to the FILENAME (or
           simply its filename extension) or "undef" if the file type is
           unknown.  The extension is used, and considered case-insensitive.
           In some cases, more than one type is known for a certain filename
           extension.  In that case, one of the alternatives is chosen at
           random.
           example: use of mimeTypeOf()
            my MIME::Types $types = MIME::Types->new;
            my MIME::Type  $mime = $types->mimeTypeOf('gif');
            my MIME::Type  $mime = $types->mimeTypeOf('jpg');
            print $mime->isBinary;
       $obj->type(STRING)
           Return the "MIME::Type" which describes the type related to STRING.
           One type may be described more than once.  Different extensions is
           use for this type, and different operating systems may cause more
           than one "MIME::Type" object to be defined.  In scalar context,
           only the first is returned.
       $obj->types()
           Returns a list of all defined mime-types
FUNCTIONS
       The next functions are provided for backward compatibility with
       MIME::Types versions 0.06 and below.  This code originates from Jeff
       Okamoto okamoto AT corp.com and others.
       by_mediatype(TYPE)
           This function takes a media type and returns a list or anonymous
           array of anonymous three-element arrays whose values are the file
           name suffix used to identify it, the media type, and a content
           encoding.
           TYPE can be a full type name (contains '/', and will be matched in
           full), a partial type (which is used as regular expression) or a
           real regular expression.
       by_suffix(FILENAME|SUFFIX)
           Like "mimeTypeOf", but does not return an "MIME::Type" object. If
           the file +type is unknown, both the returned media type and
           encoding are empty strings.
           example: use of function by_suffix()
            use MIME::Types 'by_suffix';
            my ($mediatype, $encoding) = by_suffix 'image.gif';
            my $refdata =  by_suffix 'image.gif';
            my ($mediatype, $encoding) = @$refdata;
       import_mime_types()
           This method has been removed: mime-types are only useful if
           understood by many parties.  Therefore, the IANA assigns names
           which can be used.  In the table kept by this "MIME::Types" module
           all these names, plus the most often used termporary names are
           kept.  When names seem to be missing, please contact the maintainer
           for inclussion.
