=head1 TITLE

=head1 SYNOPSIS

 almanac
 almanac tomorrow
 almanac -gmt
 almanac -help

=head1 OPTIONS

=over

=item -gmt

This option causes the time to be output in GMT.

=item -help

This option displays this documentation, then exits.

=item -location name

This option executes the named macro before generating the almanac. As
the name implies, the macro is assumed to set the location, but in
reality it can do anything.

=back

=head1 DETAILS

This Perl script uses the L<Astro::App::Satpass2|Astro::App::Satpass2>
object to generate an almanac. It assumes the presence of an
initialization file that sets the position. The date of the almanac can
be passed as an argument; otherwise the current date is used.
