* Total directory sizes are printed for -s and -l.
* Separate README file (see below).
* 10-digit field for the inode number.
* Now passes -w and "use strict".
* Tom's suggested PPT license is used.

The bug fix list is:
* Numeric user and group IDs are used when a named entry
  cannot be found.
* The time options -t, -c, and -u now default to
  sorting by descending time as documented in V7
  and BSD.
* Only 1 copy of the directory name is printed for -R.
* Special files have the stat 'dev' field printed as
  2 16-bit hex words.

On Solaris 2.6, time for a reasonable size
directory tree (667 files), where 'ls' is the
system command and 'pls' is my command:

	$ time ls -lR /www/data/ctm >/dev/null

	real    0m0.11s
	user    0m0.05s
	sys     0m0.06s
	$ time pls -lR /www/data/ctm >/dev/null

	real    0m0.71s
	user    0m0.56s
	sys     0m0.06s

Meanwhile, with beta19 of Cygnus' GNU ls ('ls')
and my ls ('pls') on 'c:/' (12,245 files)
on Windows NT4 SP3:
	bash.exe-2.01$ time ls -lR c:/ >/nul:

	real    0m23.764s
	user    0m6.539s
	sys     0m16.583s
	bash.exe-2.01$ time pls -lR c:/ >nul:

	real    0m22.452s
	user    0m0.040s
	sys     0m0.010s

=================README========================
This is an enhanced V7 version of the Unix ls(1)
command.  Notably, these BSD options are recognized:

-1 Force single-column output even to a tty
-R Recursively list directories
-S Sort by descending size
-g Accepted but ignored (uid and gid are always
   listed for -l)
-k Use 1024-byte blocks instead of 512-byte blocks
-n List numeric uid and gid (default on platforms
   without getpwuid() like Win3/95/NT)

Other BSD options won't print any error messages,
but they won't work either.

Also, this 'ls' defaults to multi-column output
when output is to a tty, like BSD 'ls' does.

This Perl implementation of I<ls>
was written by Mark Leighton Fisher of Thomson

This program is free and open software. You may use,
modify, distribute, and sell this program (and any
modified variants) in any way you wish, provided you
do not restrict others from doing the same.
