change devname(3) to return NULL on error, not "??"

4.4BSD snapshot (revision 8.1); add 1993 to copyright

use err/warn from the C library

device keys may contain padding, so make sure it is zero bytes

ANSI prototypes (two real bugs)

hash_open -> dbopen

change dev database to use "mode_t type dev_t dev" as the key

forgot to switch the include file from ndbm.h to db.h

convert from ndbm(3) to db(3) interface

only print the "no database" message once

_PATH_DEVDB is in <paths.h> now

Put print/keyword routines into separate modules; delete attime.c, use
strftime(3) instead; put combination keywords into main keyword list,
sort, delete aliases, and use bsearch(3); don't fail if nl

Put print/keyword routines into separate modules; delete attime.c, use
strftime(3) instead; put combination keywords into main keyword list,
sort, delete aliases, and use bsearch(3); don't fail if nlist fails or
devices aren't found. Whack the manual page for consistency, correctness.
