  21
  22 Change the install name of all wxWidgets libraries in the directory DIR (or
  23 current directory if libdir option is not specified) to correspond to the given
  24 install_path (defaults to the libraries directory if not specified).
  25
  26     -n, --dry-run       Don't really do anything, just print the commands
  27     -q, --quiet         Don't display any non error messages
  28     -v, --verbose       Just show the commands being executed, don't run them
  29     -h, --help          Show this help screen and exit
  30
  31 Examples:
  32  * do "$0 --libdir=MyApp.app/Contents/Frameworks @executable_path/../Frameworks"
  33    when distributing wxWidgets shared libraries with application MyApp
  34  * run "$0" without parameters in the directory containing wxWidgets libraries
  35    to use them without installing
