''Move from the main Æjaks page''

Here is a side-by-side comparison between Tcl/Tk and [Æjaks].
Neither of these will look very pretty, as I have left out any sort of whitespace padding
and grid type of layout.

 Tk                                         Aejaks
 --------------------------------------   ----------------------------------------
 # classic Tk style! Tk has reasonable    # Aejaks looks pretty awful without some
 # (but dated) default style per OS       # style, try without and you will agree.

 # Tk doesn't need a top frame for        # Aejaks can only pack one component or
 # this simple example, but we will       # container into ".", so we create a
 # add one for consistency                # top level Column

 # Tk 'frames' don't have a set shape,    # Aejaks 'Column' will always pack
 # but order child widgets based on       # children into column orientation.
 # pack options.                          # Row containers are similarly row oriented.
