\modulesynopsis{General purpose event scheduler.}

The \module{sched} module defines a class which implements a general

\begin{classdesc}{scheduler}{timefunc, delayfunc}

The \class{scheduler} class defines a generic interface to scheduling

events. It needs two functions to actually deal with the ``outside world''

--- \var{timefunc} should be callable without arguments, and return

function should be callable with one argument, compatible with the output

of \var{timefunc}, and should delay that many time units.

\var{delayfunc} will also be called with the argument \code{0} after

\end{verbatim}

\begin{methoddesc}{enterabs}{time, priority, action, argument}

Schedule a new event. The \var{time} argument should be a numeric type
