Private main method

[bugger]

I tried the following:

public class T {
private static void main(String[] str)
{
System.out.println("test");	
}
}

It does not give me any errors at compile time (I am using Eclipse 3.3). When I try to run it, it says "Main method not public". Makes sense.

But I would like to know, why main method should always be public. This method is not called by other classes directly.

Check these out, particularly the last one. It appears to vary among different versions of Java, and overall I can't find an exact answer other than, Java says so. :)
