[texhax] beamer theme customization HOWTO

[Yannis Haralambous]

The beamer user guide is a very rich and detailed document but it  
gives no hint whatsoever on how to create new layouts: how to place  
various boxes on the page and fill them with text. The question is not  
how to insert a single box in a frame, but how to change the global  
layout of frames: how to make a new theme or to change an existing one.

Maybe I overlooked some document?

I would be grateful for any hint...
