I've updated the top-level Makefile to build all the existing utilities.

I've borrowed the V1 manuals from
http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/man/man1
and changed them to reflect the PDP-7 utilities.

+NAME              cat -- concatenate and print

+SYNOPSIS          cat file1 ...
+
+DESCRIPTION       cat reads each file in sequence and writes it on the

+                                  cat file
+
+                  is about the easiest way to print a file. Also:

+                  is about the easiest way to concatenate files.

+NAME              chrm -- remove (unlink) files

+SYNOPSIS          chrm directory name1 ...

+DESCRIPTION       chrm removes the entries for one or more files from the

+	    	  the file is destroyed. Removal of a file requires write
+                  permission in its directory, but neither read nor write
+                  permission on the file itself.
+
+                  Directories cannot be removed by rm; cf. rmdir.

+DIAGNOSTICS       If the file cannot be removed or does not exist, the name

+
+BUGS              rm probably should ask whether a read-only file is really
