README file for wearth, version 1.0 Erwin Yu 5 July 1996 WHAT IS IT? If you have used some X-Window system, you may know a X-application called xearth, written by Kirk Lauritz Johnson, it can be get from ftp.x.org. I ported this program to 32-bit Windows platform ( Win95 or WinNT ) last year for my WinNT workstation, I decided to let more users enjoy it now. Wearth sets the wallpaper of Windows 95 or Windows NT to an image of the Earth, as seen from your favorite vantage point in space, correctly shaded for the current position of the Sun, updated each 5 minutes by default. INSTALL Just put the file wearth32.exe to wherever on your disk and create an item in your Windows Startup group for it, you may need to set some command line options, for example: wearth32.exe -size "800 600" -wait 300 see wearth.txt for more info. NOTES Wearth is a 32-bit Windows apllication, so it will not run on Windows 3.x unless you have win32s installed. Set you time zone correctly! Or the earth displayed will not be shaded correctly for the current position of the sun.
