In -% order to make the definition of that macro easier to understand, we first -% set up the overlays interface. -% -% Overlays must be implemented by some extra macros, such as in -% "semcolor.sty". Specifically, the commands "\@overlay" and "\make@overlay" -% should be defined. -% -% The reason for including the interface in "seminar.sty" is to encourage -% those who implement overlays to use a uniform interface, and to illustrate -% how overlays work. To be honest, though, it may not be possible to implement -% overlays without PostScript or a graphics language with similar capabilities -% using the interface that is defined here and without rewriting the basic -% slides macros. -% -% This system of overlays is so good and the system using invisible fonts is -% so lousy, that no special provisions have been made for supporting the -% latter. Actually, overlay should (and could easily) be implemented as \TeX{} -% primitives, saving everyone a lot of trouble. -% -% The system for overlays is not explained here in great detail.
