  22 Usage: $name [OPTIONS] [--prefix=PFX] [--libdir=DIR] [install_path]
  23
  24 Change the install name of all wxWidgets libraries in the directory DIR (or
  25 current directory if libdir option is not specified) to correspond to the given
  26 install_path (defaults to the libraries directory if not specified).
  27
  28 If prefix option is given, its value is prefixed to the tool names used. E.g.
  29 to use this script when cross-building, use "--prefix=powerpc-apple-darwin8-".
  30
  31     -n, --dry-run       Don't really do anything, just print the commands
  32     -q, --quiet         Don't display any non error messages
  33     -v, --verbose       Just show the commands being executed, don't run them
  34     -h, --help          Show this help screen and exit
  35
  36 Examples:
  37  * do "$name --libdir=MyApp.app/Contents/Frameworks @executable_path/../Frameworks"
  38    when distributing wxWidgets shared libraries with application MyApp
  39  * run "$name" without parameters in the directory containing wxWidgets libraries
  40    to use them without installing
