How does one specify direction of scans in r.in.ascii?

[Richard Wagener]

I am trying to do the following data import:

I have a global surface albedo file which starts at -180 lon , -90 lat
and ends at 180 lon, 90 lat, in 1 degree increments.

In grass, I have defined a region North 90, South -90, East 360, West
0, and Resolution 1.125 deg by 1.125 deg.  When I do the r.in.ascii,
and display the data, I get a rasterfile with East and West and North
and South reversed (a mirror image of an upside down world).

Question: Is there a way to specify in the ASCII file which way the
data is stored in it?  E.g.: as positive or negative
latitude/longitude increments?
Or do I have to always prepare the ASCII data to run from North-East
to South-West?  Which to me is counter intuitive.
