While +%D documenting, I also changed box building on top of overlays into the now +%D available layer positioning. So, this styles demonstrates quite some tricks. +%D +%D I'm sure that nowadays it can be done with less code but therei sno real need to +%D rewrite history. + +\setuppapersize + [S6][S6] + +\setuplayout + [topspace=0cm, + backspace=0cm, + header=0pt, + footer=0pt, + width=middle, + height=middle] + +%D Local environments can be set by using the setups commands.
