r.drain command

1.I need coordinates be read of a file. How can I do?

2. I need so many points can be input, but GUGS section say me "Currently, r.drain will not
   actually provide output for more than one pair of input coordinates stated on the
   command line".
   How can I solve it? What about grass4.1 "r.drain" version?

Thanks.

In info.grass.user you write:

It is true that in 4.1 release d.drain did not accept more than one pair
of coordinates from command line or from file.
How ever I fixed it for the update number 1, so If you have installed
update 1, ignore what the manual says. Now you can provide the coordinates
in a raster file (as described in a manual) and give more that one pair
of coordinates on the command line.
Hope this helps!
