OS X utilities provide several plugin calls for OS
10 features, including executing command line programs as the
superuser ("root"), drawing into the dock icons of your application
or a window, getting unix information about a file (such as its
path), working with the preferences menu item, and more.
What's new in OS X Utilities
Version 1.1 should fix some compatibility problems with OS 10.1;
support is no longer provided nor claimed for OS 10.0. Dock drawing
should also be faster; workarounds included in previous versions were
necessary because of bugs in 10.0 that are fixed in 10.0.
