Permission is hereby granted to anyone who wants to, to use, distribute and
modify the program in any way they want free of charge for non-commercial use.
HOWEVER.... if the program is modified, the modifier MUST:-
1)  Acknowledge the R.W.W copyright material somewhere.
2)  EITHER send the modified program back to R.W.W for a cursory accuracy check
    OR state somewhere visible to the user that the program has been modified
    and the accuracy of the changes has not been verified.
3)  Not sell the modified program without discussions with R.W.W.
Commerial use must be discussed with R.W.W first.

There - those conditions aren't too onerous are they?


About the program:-
It's a Windows 32 bit program created with Borland C++ Builder 4 - 
and much use of the VCL is made in the program, so if you use a different C compiler the code may not work. The source code is for info really.

To run the program extract 'Horizontal_Sundial.exe' into any directory you feel like, and run it from there.

The program creates an old fashioned .ini file in the directory the program resides in, called 'Sundial.ini'. This is so that you don't have to re-enter the lat/long every time you use it - and if I get around to doing other sundial programs the same data can be used so that you don't need to re-enter the data for those programs either.

Testing:-
I have done some tests on the program. It seems to work OK in the 10 cases I've tested. Be warned - there may be some combinations I've not thought of (but I doubt it, otherwise I wouldn't have published the program!). Anyway, if you find some bugs, please let me know.

Have fun with it!
