teem	/	unrrdu	unu head

unu head: Print header of a nrrd file. The value of this is simply to print
the contents of a nrrd header, avoiding the use of "head -N", where N has to
be determined manually, and thereby avoiding the risk of printing raw binary
data (following the header) to screen, as this tends to be annoying and
clobber terminal settings.

Usage: unu head <nin> [<out>]

  <nin> = input nrrd (string)
[<out>] = output file (optional string); default: "-"
