% \freebox is a utility used to format author lists.  It works
% much like \newsavebox except that users may request 
% an unnamed array of tokens.
%
% \freeboxpointer is a pointer to the next available (i.e. unused)
% token list register.  For example, \freebox4 will return the number of the 
% next available register and then advances the pointer by 4; thus you have
% 4 box registers available to you begining with the number it returned.
