48Extensions that add command line parameters or resources on their own are 48Extensions may add additional resources and C<actions>, i.e., methods
49loaded automatically when used. 49which can be bound to a key and invoked by the user. An extension can
50define the resources it support and also default bindings for one or
51more actions it provides using so called META comments, described
52below. Similarly to builtin resources, extension resources can also be
53specified on the command line as long options (with C<.> replaced by
54C<->), in which case the corresponding extension is loaded
55automatically. For this to work the extension B<must> define META
56comments for its resources.

118=head2 META comments
119
120rxvt-unicode recognizes special comments in extensions that define
121different types of metadata:
122
123=over 4
124
125=item #:META:RESOURCE:name:type:desc
126
127The RESOURCE comment defines a resource used by the extension, where
128C<name> is the resource name, C<type> is the resource type, C<boolean>
129or C<string>, and C<desc> is the resource description.
130
131=item #:META:BINDING:sym:action
132
133The BINDING comment defines a default binding for an action provided
134by the extension, where C<sym> is the key combination that triggers
135the action, whose format is defined in the description of the
136B<keysym> resource in the urxvt(1) manpage, and C<action> is the name
137of the action method.
