[NTG-context] hlingrid text t parameter?

In mp-grid.mp, I find this definition:

def hlingrid (expr Min, Max, Step, Length, Width) text t =
   image ( for i=Min step Step until Max+grid_eps :
     draw (origin--(Width,0)) shifted (0,i*(Length/Max)) t ;
   endfor ; ) ;
enddef ;

See the text t at the end of the first line? Can someone tell me what  
that does and can I have a small example of its use?
