The zsh/sched Module
====================
The zsh/sched module makes available one builtin command:
sched [+]HH:MM COMMAND ...
sched [ -ITEM ]
Make an entry in the scheduled list of commands to execute. The
time may be specified in either absolute or relative time. With
no arguments, prints the list of scheduled commands. With the
argument `-ITEM', removes the given item from the list.
