Synopsis
		sfintbin < in.rsf > out.rsf inv=n xkey= ykey= xmin= xmax= ymin= ymax= head= xk= yk= map= mask=

If inv=n, the input is 2-D (n1 x ntr). The output is 3-D (n1 x n2 x n3), n2 and
n3 correspond to two selected keys from the header file.

If inv=y, the input is 3-D, and the output is 2-D.

if xkey < 0, the first axis indexes traces in a gather like cdpt.
