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