|
|
50 | define the resources it support and also default bindings for one or |
|
|
51 | more actions it provides using so called META comments, described |
|
|
52 | below. Similarly to builtin resources, extension resources can also be |
|
|
53 | specified on the command line as long options (with C<.> replaced by |
|
|
54 | C<->), in which case the corresponding extension is loaded |
|
|
55 | automatically. For this to work the extension B<must> define META |
|
|
56 | comments for its resources. |
