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.
