+Most languages allow the main program to have any name.  The
+@code{N_MAIN} stab type is used for a stab telling the debugger what
+name is used in this program.  Only the name is significant; it will be
+the name of a function which is the main program.  Most C compilers do
+not use this stab; they expect the debugger to simply assume that the
+name is @samp{main}, but some C compilers emit an @code{N_MAIN} stab for
+the @samp{main} function.
