/* MainDocument.m
* Chris Saldanha, June 1999 (modified April 2001 for MacOS X 10.0)
* Class to display fortunes in a simple window.
* Can copy the fortune into the pasteboard from a menu option.
* Clicking in the window's content view makes it go away.
* For MacOS X - now using swanky classes NSTask/NSFileHandle/NSPipe instead of UNIX calls
