//
//
// This is the setup program for Win32 GNU Ghostscript
//
// The starting point is a self extracting zip archive
// with the following contents:
//   setupgs.exe
//   uninstgs.exe
//   filelist.txt      (contains list of program files)
//   fontlist.txt      (contains list of font files)
//   gs#.##\*          (files listed in filelist.txt)
//   fonts\*           (fonts listed in fontlist.txt)
// This is the same as the zip file created by Aladdin Enterprises,
// with the addition of setupgs.exe, uninstgs.exe, filelist.txt and 
// fontlist.txt.
//
// The first line of the files filelist.txt and fontlist.txt
// contains the uninstall name to be used.  
// The second line contains name of the main directory where 
// uninstall log files are to be placed.  
// Subsequent lines contain files to be copied (but not directories).
// For example, filelist.txt might contain:
//   GNU Ghostscript 6.50
//   gs6.50
//   gs6.50\bin\gsdll32.dll
//   gs6.50\lib\gs_init.ps
// The file fontlist.txt might contain:
//   GNU Ghostscript Fonts
//   fonts
//   fonts\n019003l.pfb
//   fonts\n019023l.pfb
//
// The default install directory is c:\gs.
// The default Start Menu Folder is Ghostscript.
// These are set in the resources.
// The setup program will create the following uninstall log files
//   c:\gs\gs#.##\uninstal.txt
//   c:\gs\fonts\uninstal.txt
// The uninstall program (accessed through control panel) will not 
// remove directories nor will it remove itself.
//
// If the install directory is the same as the current file 
// location, no files will be copied, but the existence of each file 
// will be checked.  This allows the archive to be unzipped, then
// configured in its current location.  Running the uninstall will not 
// remove uninstgs.exe, setupgs.exe, filelist.txt or fontlist.txt.
