\begin{funcdesc}{max}{s\optional{, args...}\optional{key}}
With a single argument \var{s}, return the largest item of a
non-empty sequence (such as a string, tuple or list). With more
than one argument, return the largest of the arguments.
The optional \var{key} argument specifies a one argument ordering
function like that used for \method{list.sort()}. The \var{key}
argument, if supplied, must be in keyword form (for example,
\samp{max(a,b,c,key=func)}).
