50 | define the resources it support using so called META comments, |

|

52 | can also be specified on the command line as long options (with C<.> |

|

118 | |
|
|
119 | Rxvt-unicode recognizes special meta comments in extensions that define |
|
|
120 | different types of metadata. |
|
|
121 | |
|
|
122 | Currently, it recognises only one such comment: |

|
|
127 | |
|
|
128 | The RESOURCE comment defines a resource used by the extension, where |
|
|
129 | C<name> is the resource name, C<type> is the resource type, C<boolean> |
|
|
130 | or C<string>, and C<desc> is the resource description. |
