                        ***  Version 1.00  ***

                     
Astrolog is a classic when it comes to astrology software, not only is 
it 100 percent open source software, but it is also the most complete,
and most flexible astrology calculation program ever made freely
available.

Thanks to the original author Walter D. Pullen Astrolog is already 
available on multiple platforms, including DOS, Windows, Mac and Unix. 
The fact that Astrolog is open source software has also made this
independent port to OS/2 possible.


Astrolog for OS/2
-----------------

This port of Astrolog to 32-bit OS/2 compares to the windows version 
as follows. A plus sign in front of an item indicates functionality 
not in the original but in Astrolog for OS/2. A minus sign precedes 
original functionality not found in this release.

 - Basic interpretations
 - Arabic parts*
 - Biorythm*
 - Windows bitmap save*
 + Longer filenames can be used.
 + Time and dates in the ISO format, this is the default (the old
   format can be selected through a settings dialog).
 + Time zone automatically picked up if the environment variable TZ
   has been set in config.sys, to test select the "Now" push button
   in the chart dialog or press ctrl+z.
 + Clear UT based time zone designations. Also no need for any
   separate and confusing "daylight saving" setting.
 + Summary in the sidebar for graphics charts presenting weighted
   element and mode counts.
 + Chart files can be associated with the Astrolog executable.
 + Saving size and position of main window between runs.
 + Copying of select text to the clipboard.
 + OS/2 bitmap save.
 + Easy switching between four chart buffers. The contents of these 
   buffers is automatically preserved between runs. This includes 
   current file name (if there is any). Also loads filename when 
   opening a chart by double-clicking on it.
 + Adjustment of aspect lines to orb (instead of a fixed 2 degrees).
 + Jyotish houses (sidereal equal houses).
 + Dwads.
 + Extended user customization (influence calculations, aspect
   trimming, etc.)
 + Sine function for orb power.

The following may be added later:

 * Swiss Ephemeris
 * Basic interpretations

Finally, the fact that this program is free doesn't mean it should 
lack any important features or have any persistent bugs. In other 
words I'd like this version for OS/2 to work well, so if it doesn't 
don't hestitate the slightest to tell me about it.

Program updates and an ever growing chart collection working with both 
original Astrolog as well as Astrolog for OS/2 can be found at the
Astrolog for OS/2 home page.

Astrolog for OS/2 system requirements
-------------------------------------

Any system running Warp 4 or later.

The source code for this version was compiled and linked using
Watcom C 10.6, Warp 4 libraries and the resource compiler found in 
the Warp 4 toolkit.


Where to get Astrolog for OS/2
------------------------------

This independent port of Astrolog to OS/2 is archived at the 
public OS/2 shareware and open source software archive Hobbes:

     http://hobbes.nmsu.edu

In case you can't reach Hobbes, or you want the latest info on
Astrolog for OS/2 you can visit its home page (see top).


The Astrolog Homepage (The Original)
------------------------------------

Ephemeris and general info about Astrolog as well as links to 
related sites can be found at the Astrolog homepage:

     http://www.astrolog.org/astrolog.htm

Here you will also be able to find the original source for
Astrolog as well as binaries for Windows.


Ephemeris
---------

Ephemeris files are not required but provide more accurate positions. 

The anonymous FTP site ftp.magitech.com (or magitech.tcastle.is.net),
maintained by J.H. Trott has all ephemeris files available in the
subdirectory /pub/astrology/astrolog/ephem.

The files are in groups with xx being a number indicating the time 
period covered. The three files LRZ5_24, CHI_24, and CPJV_24 cover the 
current and 21st centuries. Copies of these files are already in the
end user package.
