These programs are used to get files back from old Unix disk images and
tape backup images. Many were written ages ago, and my need to be ported to
32-bit and/or big-endian machines.

Here's a chart of what is supposed to do what, and my success with using it
on a 32-bit little-endian machine (an i486 running FreeBSD).

	     v5        v6        v7      2.9BSD	     32V
	   filesys   filesys   filesys   filesys   filesys
cpfs			?
getunix			?	  ?	    ?	      ?
grab          Y         Y         ?         ?
traverse		?

	     tp      itp      dtp      v6
	   backup   backup   backup   dump
512restor			       ?
tp-progs     Y        Y        Y

  ? = it's supposed to, but I haven't tried it yet
  Y = it worked on my FreeBSD box
