"The main() function Xcode creates begins by calling a function named 
NSApplicationMain(), which is functionally similar to the following:"...

void NSApplicationMain(int argc, char *argv[]) {
    [NSApplication sharedApplication];
    [NSBundle loadNibNamed:@"myMain" owner:NSApp];
    [NSApp run];
}



See also <http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Miscellaneous/AppKit_Functions/Reference/reference.html#//apple_ref/c/func/NSApplicationMain

"Creates the application, loads the main nib file from the 
application’s main bundle, and runs the application. You typically 
only call this function once, from your application’s main function, 
which is usually generated automatically by Xcode."

So, particularly with reference to <http://developer.apple.com/DOCUMENTATION/MacOSX/Conceptual/BPRuntimeConfig/Articles/PListKeys.html
> you can fill in a little more detail:


void NSApplicationMain(int argc, char *argv[])
{
    NSDictionary * infoDictionary = [[NSBundle mainBundle] 
infoDictionary];

    NSString *principalClassName = [infoDictionary 
objectForKey:@"NSPrincipalClass"];
    Class principalClass = NSClassFromString(principalClassName);
    [principalClass sharedApplication];

    NSString *mainNibFile = [infoDictionary 
objectForKey:@"NSMainNibFile"];
    [NSBundle loadNibNamed:@"mainNibFile" owner:NSApp];

    [NSApp run];
}
