Shifting or rotating a raster file, how?

[Wang-hua Li]

Hi there,
	
	After patching two raster files, an uncontinuous edge arises on the
new patched layer. I guess one of them need to be shifted or even rotated so
they'll match each other. Is there any way I could have this done in GRASS?

Thanks in advance !
