PalMoon version 0.0.3

1) What is "PalMoon"?

"PalMoon" is a program for displaying information about the moon. I think it works fine on PalmOS 3.1 (or later) devices. I used IBM WorkPad c3(8602-50X) to development.

Not only the binary but also the source code is available. This program is free software and it is distributed under GPL.

Core calculation source code is borrowed from UNIX public domain software "moontool", written by John Walker. His comments can be found in `README.ORIG.TXT'. The image of the moon was made by Joe Hitchens.

2) Before using.

a) Required library.

This program requires 'MathLib', an IEEE-754 double-precision math library. You can get the library from http://www.probe.net/~rhuebner/mathlib.html .

b) Timezone setting.

First, you have to set the timezone correctly. To set the timezone(abbreviation and time difference), open the menu and click "Option" -> "Timezone".

Your timezone may be found in "Preset" pulldown menu. Otherwise you can set these items directly.

[notice] set the time difference in second.

3) View.

Displayed information will be updated at least every one second.

Unfortunately there is no space to print the image of the moon. 160x160 is a little small.
