[GRASSLIST:1345] r.in.ascii reflection

[Gordon Keith]

I'm using grass5b10 and r.in.ascii to read an raster image generated by 
another package.

Unfortunately, this package seems to have written lines in the reverse 
order from grass so that the northern end of the image appears at the 
southern end in grass and vice-versa.

Is there any program in grass to perform raster transformations, such as 
reflection? or can anyone point to any unix utilities that reverses the 
line order of an ASCII file?

Thanks in advance

Gordon
