help="
Welcome to wake, an MP3 Alarm Clock.
This script is designed to be run from crontab for the days you
wish to be woken on, and at the time you wish to be woken.
Each day it will take the next n songs from your playlist, and play
them with the required snooze time between each song.
At the moment, it only works with mpg123, but it's easy enough to
change it for other media players.

The script takes several options:

-c [count] The number of files to play (default 1)
-z [snooze] The number of seconds to snooze between songs (default 300)
-l [list] The path of your playlist (defaults to ~/allsongs)
-s skip files not found instead of exiting with error
-d debug, outputs what it will do without actually doing anything
-h Show this help info

Try something like this in your crontab:

40 7 * * 1-5 /home/lambic/wake -c 5 -p 300 -s

Which will wake you up at 07:40 Mon-Fri
with 5 songs separated by 5 minutes snooze"
