How can we do this using awk/sed.

Tk::Whatever - a whatever widget
=head1 SYNOPSIS
use Tk::Whatever;
$widget = $parent->Whatever(...);
=head1 DESCRIPTION
...
DESCRIPTION
The intention behind a composite is to create a higher-level widget, sometimes called a "super-widget" or "mega-widget". Most often, a
composite will be built upon other widgets by using them, as opposed to specializing on them. For example, the supplied composite widget
LabEntry is made of an Entry and a Label; it is neither a kind-of Label nor is it a kind-of Entry.
Most of the work of a composite widget consistd in creating subwidgets, arranging to dispatch configure options to the proper subwidgets
and manage composite-specific configure options.
GLORY DETAILS
Depending on your Perl/Tk knowledge this section may be enlighting or confusing.
Composite Widget
Since Perl/Tk is heavilly using an object-oriented approach, it is no suprise that creating a composite goes through a new() method.
However, the composite does not normally define a new() method itself: it is usually sufficient to simply inherit it from Tk::Widget.
This is what happens when the composite uses
use base qw/ Tk::Frame /; # or Tk::Toplevel
to specify its inheritance chain. To complete the initialisation of the widget, it must call the Construct method from class Widget. That
method accepts the name of the new class to create, i.e. the package name of your composite widget:
Construct Tk::Widget 'MyNewWidget';
Here, MyNewWidget is the package name (aka the widget's class). This will define a constructor method for MyNewWidget, normally named
after the widget's class. Instanciating that composite in client code would the look like:
$mw = MainWindow->new; # creates a top-level MainWindow
$self = $mw->MyNewWidget(); # creates an instance of the
# composite widget MyNewWidget
Whenever a composite is instanciated in client code, "Tk::Widget::new()" will be invoked via the widget's class constructor. That new
method will call
$self->Populate(\%args);
where %args is the arguments passed to the widget's constructor. Note that Populate receives a reference to the hash array containing all
arguments.
Populate is typically defined in the composite class (package), which creates the characteristic subwidgets of the class.
Creating Subwidgets
Subwidget creation happens usually in Populate(). The composite usually calls the subwidget's constructor method either directly, for
"private" subwidgets, or indirectly through the Component method for subwidgets that should be advertised to clients.
Populate may call Delegates to direct calls to methods of chosen subwidgets. For simple composites, typically most if not all methods are
directed to a single subwidget - e.g. ScrListbox directs all methods to the core Listbox so that $composite->get(...) calls
$listbox->get(...).
Defining mega-widget options
Populate should also call ConfigSpecs() to specify the way that configure-like options should be handled in the composite. Once Populate
returns, method Tk::Frame::ConfigDefault walks through the ConfigSpecs entries and populates %$args hash with defaults for options from X
resources (.Xdefaults, etc).
When Populate returns to Tk::Widget::new(), a call to $self->configure(%$args) is made which sets *all* the options.
