30
31 The following non-core modules are required:
32
33 Sub::Exporter
34
35 =head1 INSTALLATION
36
37 Installation can be done using the traditional Makefile.PL or the newer
38 Build.PL methods.
39
40 Using Makefile.PL:
41
42 perl Makefile.PL
43 make test
44 make install
45
46 (On Windows platforms you should use C<nmake> instead.)
47
48 Using Build.PL (if you have Module::Build installed):
49
50 perl Build.PL
51 perl Build test
52 perl Build install

64 =head1 SYNOPSIS
65
66 use Media::Type::Simple;
67
68 $type = type_from_ext("jpg"); # returns "image/jpeg"
69
70 $ext = ext_from_type("text/plain"); # returns "txt"
71
72
73 =head1 DESCRIPTION
74
75 This package gives a simple functions for obtaining common file
76 extensions from media types, and from obtaining media types from
77 file extensions.
78
79 It is also relaxed with respect to having multiple media types
80 associated with a file extension, or multiple extensions associated
81 with a media type, and it includes media types for encodings such
82 as F<gzip>. It is defined this way in the default data, but
83 this does not meet your needs, then you can have it use a system file
84 (e.g. F</etc/mime.types>) or custom data.
85
86 By default, there is a functional interface, although you can also use
87 an object-oriented inteface. (Different objects will not share the same
88 data.)

103
104 $o = Media::Type::Simple->new;
105
106 Creates a new object. You may optionally give it a filehandle of a file
107 with system Media information, e.g.
108
109 open $f, "/etc/mime.types";
110 $o = Media::Type::Simple->new( $f );
111
112 =begin internal
113
114 When L</new> is called for the first time without a file handle, it
115 checks to see if the C<$Default> instance is initialised: if it is
116 not, then it initialises it and returns a L</clone> of C<$Default>.
117
118 We operate on clones rather than the original, so that any changes
119 made, e.g. L</add_type>, will not affect all other instances.

144
145 =item _args
146
147 An internal function used to process arguments, based on C<_args> from
148 the L<self> package. It also allows one to use it in non-object
149 oriented mode.
150
151 When L</_args> is called for the first time without a reference to the
152 class instance, it checks to see if C<$Work> is defined, and it is
153 initialised with L</new> if it is not defined. This means that
154 C<$Work> is only initialised when the module is used.
155
156 =item self
157
158 An internal function used in place of the C<$self> variable.
159

161
162 An internal function used in place of shifting arguments from stack.
