Hello, you hackers who enjoyed my previous standard C program,
stdmain.c.  I now bring you a standard /bin/sh script.  It is
basically an argument parser, and will accept arbitrary argument
formats:

	std -a -l -x -th0 -o outfile -
	std -alxth0 -ooutfile

and related permutations can parse as:

	-a
	-l
	-x
	-t with argument h0
	-o with argument outfile
	-

just like stdmain.c.  Convert all of your shell scripts now, so you
don't need to remember whether the -o arument should be attached or
not!

# The following is just for testing this standard script
echo '
Argument' analysis to $0:
echo Flags: -v = $verbose, -o = \"$outfile\"
echo Unknown flags: $unkflag
echo Files: $files
//E*O*F std.sh//

exit 0
