=head1 TITLE
spacetrack-identity - Report the user's Space Track identity
=head1 SYNOPSIS
spacetrack-identity
spacetrack-identity -help
spacetrack-identity -version
or, if you have any of a number of Unix shells,
export eval `spacetrack-identity`
=head1 OPTIONS
=head2 -basic
If asserted, this option causes the output to be punctuated with a colon
(C<':'>, think HTTP basic authentication) rather then a slash (C<'/'>,
think Oracle). Both are understood by
L<Astro::SpaceTrack|Astro::SpaceTrack>.
The default is C<-nobasic>.
=head2 -help
This option displays the documentation for this script. The script then
exits.
=head2 -version
This option displays the version of this script. The script then exits.
=head1 DETAILS
This Perl script reports the user's Space Track identity. On success,
the output is
SPACETRACK_USER=username/password
unless C<-basic> is specified, in which case you get a colon (C<':'>)
rather than a slash (C<'/'>).
On failure, the script dies.
