 Every time a terminal object gets created, extension scripts specified via

 hints on what they mean:

 Rxvt-unicode recognizes special meta comments in extensions that define

 Currently, it recognises only one such comment:

 =item #:META:RESOURCE:name:type:desc
 The RESOURCE comment defines a resource used by the extension, where
 C<name> is the resource name, C<type> is the resource type, C<boolean>
 or C<string>, and C<desc> is the resource description.
+The extension will be autoloaded when this resource is specified or used

 The following "macros" deal with changes in rendition sets. You should
 never just create a bitset, you should always modify an existing one,
 as they contain important information required for correct operation of
 rxvt-unicode.

 =item $rend = urxvt::DEFAULT_RSTYLE
 Returns the default rendition, as used when the terminal is starting up or
 being reset. Useful as a base to start when creating renditions.

 as long as the perl object is referenced.
 The methods currently supported on C<urxvt::overlay> objects are:

 =item $overlay->set ($x, $y, $text[, $rend])
 Similar to C<< $term->ROW_t >> and C<< $term->ROW_r >> in that it puts

       # mouse reporting is turned on

 about the logical line that row C<$row_number> is part of. It supports the

 immediately.

 the process is idle. They should return as fast as possible, after doing
 some useful work.

 Create a new idle watcher object in stopped state.

+=over
 =item $pw = new urxvt::pw
 Create a new process watcher in stopped state.

 This variable controls the verbosity level of the perl extension. Higher
 numbers indicate more verbose output.
