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