This is an attempt to make the utilities specified in
POSIX 1002.3 available, assuming /$objtype/ape/bin
and /lib/rc/ape are bound to /bin before the regular
bin directories.
Here's a brief description of the status of these commands.
EXECUTION ENVIRONMENT UTILITIES
awk Plan 9 awk.
system() uses rc instead of sh.
basename POSIX conforming
bc Plan 9 bc.
cat Plan 9 cat.
no -u option (for byte-at-at-time)
cd shell builtins
doesn't use $HOME or $CDPATH
chgrp Plan 9 chgrp.
no -R option (for recursive chgrp).
only takes name, not number
chmod Plan 9 chmod.
no -R option (for recursive chmod).
no s (setuid) and X (conditional x) perms.
nonstandard a,l perms.
chown Always prints 'Permission denied' and fails.
cksum not implemented
cmp Plan 9 cmp.
nonstandard -L option
no line number printed; hex instead of octal for bytes
comm Plan 9 comm.
command not implemented

-c<n> instead of -c and -C <n> for context
dirname POSIX conforming
echo Plan 9 echo
ed Plan 9 ed
nonstandard b,wq commands
env not implemented
expr V10 expr (seems to be like POSIX)
false POSIX conforming
find not implemented
fold not implemented
getconf not implemented
getopts not implemented
grep script calling Plan 9 grep -G
s means q, should mean forget nonexistent files
nonstandard 1,b,L,q options
head not implemented
id not implemented
join not implemented
kill V10 kill
no -s signalname, no -l arg
ln not implemented
locale not implemented
localedef not implemented
logger not implemented

tail Plan 9 tail
tee Plan 9 tee

SOFTWARE DEVELOPMENT UTILITIES (OPTIONAL)

make V10 make

C LANGUAGE DEVELOPMENT UTILITIES OPTION

General Bugs:
The environment variables LANG, LC_ALL,
LC_CTYPE, and LC_MESSAGES are ignored.
The use of -- as an argument to stop option processing
is generally not done.
The many 'not implemented' functions will be implemented
as scripts using them show up.
