The pom utility displays the current phase
of the moon. Useful for selecting software completion target dates and
predicting managerial behavior.
Use the -p option to print just the phase
as a percentage.
Use the arguments -d and
-t to specify a specific date and time for which the
phase of the moon has to be calculated. If -d but
not -t has been specified, it will calculate the
phase of the moon on that day at midnight.
