REM  prepare_ghostscript.bat
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.
