iis - pipe fits image data into saopipe

iis [options...]

"-u " print this message

"-f fmin fmax " limits for pixel values

"-p pipename " supply FIFO pipe name

"iis" reads a fits image from stdin, prepends an iis header and writes the output to a FIFO pipe /dev/imt1o so that saoimage can display it. If the standard FIFO does not exist (it typically won't unless you have IRAF installed) then create one with e.g. 'mknod ~/dev/saopipe p' and then fire up saoimage with 'saoimage -idev ~/dev/saopipe &' Beware: some old versions of saoimage crash when you try to supply 'idev' argument. Many thanks to Karl Glazebrook for refinements to original code.
