Give yourself some credit in your program: make an About window. They don't need to be especially fancy, but they can be if you are so inclined. It should contain the title of your program, the version, you and any other authors or the name of your company, and copyright information. If nothing else, write a few lines of code to show a BAlert with this information and you'll have enough. If there is a lot of information to show, using a marquee effect to automatically scroll the information or at least a read-only text view with a scroll bar. Do not include information about the computer itself, such as the amount of RAM or processor speed; it doesn't belong here. While you certainly may show something short about the licensing of your program like "Distributed under the terms of the GNU Public License," the full text of the license belongs elsewhere. The window should not have a tab and should either have a button marked 'Close' or simply disappear when clicked. It should also respond to the Command + W keyboard shortcut.
