@section Main Program
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.
