+REM  Finds the system GhostScript installation and copies the
+REM  files needed for bundling into conf\ghostscript\
+REM
+REM  Files copied:
+REM    conf\ghostscript\bin\gswin64c.exe  (or gswin32c.exe)
+REM    conf\ghostscript\bin\gsdll64.dll   (or gsdll32.dll)
+REM    conf\ghostscript\lib\*.ps          (PostScript init files)
+REM
+REM  Run this ONCE before building the exe with build_windows.bat.
+REM  Only the two executables + the lib/ folder are needed (~15-20 MB).
+REM  The full GhostScript fonts/Resources are NOT bundled to keep
+REM  the exe size manageable; Windows system fonts are used instead.
