+Usage: $0 [OPTIONS] [--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).
+
+    -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 "$0 --libdir=MyApp.app/Contents/Frameworks @executable_path/../Frameworks"
+   when distributing wxWidgets shared libraries with application MyApp
+ * run "$0" without parameters in the directory containing wxWidgets libraries
+   to use them without installing
