I see sh.1, nval.3, and shell.3 on the list. Don't you need the shell man page and the programming interface man pages for writing built-ins?
Also, do you intened to add the shcomp command which generates binary format files that the shell can process from shell scripts. If you intened to support setuid shell scripts or execute only shell scripts (no read permission), you also need suid_exec.c. David Korn dgk at research.att.com
