This is the OS/2 port of Elwood Downey-Guest's xephem 3.1.
This was ported by Mark Goldberg (goldber at primenet dot com). It was 
surprisingly easy once I understood how.  This is the third
version of the port, now based on xephem 3.1. It requires
lesstif which is no longer included in this archive.  The
released version 0.83 works which may be gotten from:

ftp://ftp.hungry.com/pub/hungry/lesstif/bindist/lesstif-0.83-OS2.zip

See Michael Holzapfel's lesstif OS/2 page at:

http://www.ime.rwth-aachen.de/~michael/os2/lt/lesstif.html

for installation instructions for lesstif.

There are a no bugs still in lesstif that affect XEphem as far
as I can tell.  I used the program for a couple of hours and
could find no problems.  Email me if you find any!

Unzip xephem31.zip into the root of the drive containing Xfree86.

If this archive was unzipped in the root of the drive containing
XFree, and you have things in the standard places, it should
work.  Just type xephem at an xterm to run xephem.cmd.

XEphem.ad is the default resources for XEphem.  A copy will be in:

\Xfree86\lib\X11\app-defaults

as the filename:

XEphem

This will automatically be found by XFree.  You should make
any changes there.

Compiling under OS/2:

You can compile this yourself under OS/2.  You might want to
do this to use the latest lesstif.

To do this, get lesstif-current.tar.gz from:

ftp://ftp.hungry.org/pub/hungry/lesstif/

See Michael Holzapfel's lesstif OS/2 page at:

http://www.ime.rwth-aachen.de/~michael/os2/lt/lesstif.html

for instructions to build and install lesstif.

Get the sources for xephem in xephem-3.1.tar.gz. See:

http://iraf.noao.edu/~ecdowney/xephem.html

for information.

Use gzip and tar to get it into the directory:

\XFree86\bin\xephem-3.1

To do this, change to \Xfree86\bin and untar it
from there.

Then unzip xephem31.zip into the root of the drive
containing \XFree86 to add readme files, makeos2.cmd
and a change to the Makefile in the gsc subdirectory.

Change to the \XFree86\bin\xephem-3.1 directory
and execute makeos2.cmd

This will build the new version of xephem if all goes well.
You may need many gnu utilities to do this, sed, awk, flex,
bison, etc...

Thanks to Elwood Downey for writing xephem in such a portable fashion,
Danny Backx and Rick Scott and the rest of the lesstif team,
Michael Holzapfel and Christoph Jaeschke, and Holger Veit and all of
the people he thanks for XFree OS/2.

If you have any problems that you think are related to this port, feel
free to contact me.

Good Luck
