[Tkinter-discuss] a couple of mac menu problems

Along the same lines, I managed to get application/preferences to work on the Mac, but while application/about shows the name of my Python app (built with pyinstaller), it displays the 'Tcl & Tk' dialog.  

The TkDocs-TK Tutorial on menus shows this as a TODO item (http://www.tkdocs.com/tutorial/menus.html).  While I was able to figure out the preferences menu by looking at the idlelib sources, I couldn't get the application/about menu to work.

Any suggestions?

> There's some magic in the Tk-Cocoa help menu--if you define the tk::mac::showHelp command and map it to your function that calls user help, you don't need to add a separate entry for help. (There's already an entry hard-coded for help, along with the search field.) So the helpMenu.add_Command(label="Help")... stuff is redundant.
