\&  pom [\-d] [\-e] [[[[[[cc]yy]mm]dd]HH]]
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The pom utility displays the current phase of the moon.  This is
useful for selecting software completion target dates, predicting
managerial behavior, or determining thoth's current mood. :)
.PP
Pom will display the current moon phase, unless a new time is
specified on the command line.  The parameter's format is similar to
the canonical representation used by \fIdate\fR\|(1).
.PP
Pom has two modes: \*(L"standard\*(R" and \*(L"enhanced\*(R".  Standard mode presents
a brief description of the moon's phase.  It is the default.  Enhanced
mode shows the phase's date and time, the brief description, and an
\&\s-1ASCII\s0 art representation of the moon's phase.
.PP
Current options:
.PP
.Vb 2
\&  \-d    Enable debugging.  This calculates phase information every
\&        hour for a month.
\&
\&  \-e    Enable enhanced mode.  Turns on the ASCII art feature.

.SH "BUGS"
.IX Header "BUGS"
Times must be within the range of the Unix epoch.
.PP
The local timezone and coordinates are not considered.
.PP
Day validation does not consider the current month, or leap days.
.PP
The default character cell aspect ratio is likely to be wrong.
.PP
There is some jitter in the current calculations.  It may only be
noticeable while debugging.
.PP
The calculations in this version are a few percent different from the
original pom.
.SH "ACKNOWLEDGEMENTS"
.IX Header "ACKNOWLEDGEMENTS"
A lot of the documentation was cribbed from the OpenBSD Reference
Manual.
.PP
The moon phase calculations were ported from pcal, which is available
from <ftp://www.decus.org/pub/lib/vs0174/pcal/>.
