Usage: $name [OPTIONS] [--prefix=PFX] [--libdir=DIR] [install_path]

Change the install name of all wxWidgets libraries in the directory DIR (or
current directory if libdir option is not specified) to correspond to the given
install_path (defaults to the libraries directory if not specified).

If prefix option is given, its value is prefixed to the tool names used. E.g.
to use this script when cross-building, use "--prefix=powerpc-apple-darwin8-".

    -n, --dry-run       Don't really do anything, just print the commands
    -q, --quiet         Don't display any non error messages
    -v, --verbose       Just show the commands being executed, don't run them
    -h, --help          Show this help screen and exit

Examples:
 * do "$name --libdir=MyApp.app/Contents/Frameworks @executable_path/../Frameworks"
   when distributing wxWidgets shared libraries with application MyApp
 * run "$name" without parameters in the directory containing wxWidgets libraries
   to use them without installing
