Version 1.3 with unofficial patches (by Kyosuke Tokoro <NBG01720@nifty.ne.jp>)
  - Now, runs OS/2 systems.
      + Print the file attributes in 'adhrs' format for each file, instead
	of the protections in 'drwxrwxrwx' format, when running the tree
	on OS/2 with option -p.
  - RFC2396 URI encoding to HTML output.
  - Added style sheet to HTML output, to display links without underlines.
  - Added the host name which is specified in the `-H' option, to <TITLE>
    section.
  - Added --charset option, to specify which character set is used for
    output.
      + You can specify any IANA registered character set name. But I have
	tested only following character sets:
		Shift_JIS	EUC-JP		IBM850
		UTF-8		ISO-8859-1	US-ASCII
      + Now, `-S' option is equal to `--charset=IBM437'.
      + When running on OS/2 systems, the default value of this option
	is according to current codepage.  On the other systems, no default.
  - Improved command line perser.  Now, any spaces are not required between
    option swith character and its argument.  For example, `-ofile' will
    be recognized as `-o file'.

Version 1.3
  - Fixed long pathname problem by dynamically allocating the path.
  - Added recursive symlink detection.
  - Added --help and --version options.
  - When -C is used and LS_COLORS is undefined, tree uses a default color
    scheme (thus -C always forces color output now).
  - Added -S to show ASCII tree lines (Gerald Scheidl)
  - Made tree more portable (Guido Socher and others)

  Following options curtsey of Francesc Rocher:
  - Added -o <filename> to redirect the output.
  - Added -H <baseHRef> to print the tree in HTML format.
  - Added -L to set the maximum level of directories to print.
  - Added -R to recursively reestart the search at the level given by `-L'
    option (adding as well `-o 00Tree.html').

Version 1.2
  - Added -D to print the date of the last modification.
  - Added -t option to sort by last modification time (ala ls -t).
  - Added -I <pattern>, simular to the -P option except tree does not print
    those files which match the pattern.
  - Made tree print non-printable characters in filenames in standard unix
    carrot notation.
  - Added -N option to make tree print filenames without any processing.
  - Added -q option to make tree print non-printable characters in filenames
    as question marks.
  - Added `|' to -F output and made it only print character type after the
    link on sym-links, not on the symlink name itself.
  - Added -u option to display username/uid, and -g option to display group
    name/gid.
  - Fully (pass the salt) implemented dircolors support.

Version 1.1
  - Made some changes to the Makefile to insure proper installation and for
    multi-architecture support and a bug-fix.
  - Made root directory colorized if dircolors is enabled.
  - Put []'s around permission and size info, 'cause I think it looks better.
  - Added -A option to enable ANSI-lines hack.
  - Added some sanity checks for dircolors support.
  - Added -P <pattern> to list only those files that match the wildcard
    given in <pattern>.
  - Fixed error where relative symbolic links to directories would not be
    followed when the -l option was used.
  - Made uid 0 the same as anyone else (-a was default for uid 0)
  - Added -x directive to stay on one filesystem (ala find -xdev).

Version 1.0
  - The original, a model of perfection...
