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
+                  standard output stream. Thus:
+
+                                  cat file
+
+                  is about the easiest way to print a file. Also:
+
+                     cat filel file2 >file3
+
+                  is about the easiest way to concatenate files.
+
+FILES
+
+SEE ALSO          pr, cp
+
+DIAGNOSTICS       If a file cannot be found it is ignored. If no files are
+		  given, "no files" is output.

+DESCRIPTION       The octal mode replaces the mode of each of the files. The

+
+                     01 write for non--owner

+
+
+NAME              chrm -- remove (unlink) files
+
+SYNOPSIS          chrm directory name1 ...
+
+DESCRIPTION       chrm removes the entries for one or more files from the
+                  named directory. If an entry was the last link to the file,
+	    	  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.
+
+FILES             none.
+
+SEE ALSO          rmdir, for removing directories.
+
+DIAGNOSTICS       If the file cannot be removed or does not exist, the name
+                  of the file followed by a question mark is typed.
+
+BUGS              rm probably should ask whether a read-only file is really
+                  to be removed.
