   5  *  History:
   6  *
   7  *  17/08/94 (Tim Norman)
   8  *    started.
   9  *
  10  *  08/08/95 (Matt Rains)
  11  *    i have cleaned up the source code. changes now bring this source into
  12  *    guidelines for recommended programming practice.
  13  *
  14  *  cd()
  15  *    started.
  16  *
  17  *  dir()
  18  *    i have added support for file attributes to the DIR() function. the
  19  *    routine adds "d" (directory) and "r" (read only) output. files with the
  20  *    system attribute have the filename converted to lowercase. files with
  21  *    the hidden attribute are not displayed.
  22  *
  23  *    i have added support for directorys. now if the directory attribute is
  24  *    detected the file size if replaced with the string "<dir>".
  25  *
  26  *  ver()
  27  *    started.
  28  *
  29  *  md()
  30  *    started.
  31  *
  32  *  rd()
  33  *    started.
  34  *
  35  *  del()
  36  *    started.
  37  *
  38  *  does not support wildcard selection.
  39  *
  40  *  todo: add delete directory support.
  41  *        add recursive directory delete support.
  42  *
  43  *  ren()
  44  *    started.
  45  *
  46  *  does not support wildcard selection.
  47  *
  48  *    todo: add rename directory support.
  49  *
  50  *  a general structure has been used for the cd, rd and md commands. this
  51  *  will be better in the long run. it is too hard to maintain such diverse
  52  *  functions when you are involved in a group project like this.
  53  *
  54  *  12/14/95 (Tim Norman)
  55  *    fixed DIR so that it will stick \*.* if a directory is specified and
  56  *    that it will stick on .* if a file with no extension is specified or
  57  *    *.* if it ends in a \
  58  *
  59  *  1/6/96 (Tim Norman)
  60  *    added an isatty call to DIR so it won't prompt for keypresses unless
  61  *    stdin and stdout are the console.
  62  *
  63  *    changed parameters to be mutually consistent to make calling the
  64  *    functions easier
  65  *
  66  *  rem()
  67  *    started.
  68  *
  69  *  doskey()
  70  *    started.
  71  *
  72  *    01/22/96 (Oliver Mueller)
  73  *        error messages are now handled by perror.
  74  *
  75  *    02/05/96 (Tim Norman)
  76  *        converted all functions to accept first/rest parameters
  77  *
  78  *    07/26/96 (Tim Norman)
  79  *        changed return values to int instead of void
  80  *
  81  *        path() started.
  82  *
  83  *    12/23/96 (Aaron Kaufman)
  84  *        rewrote dir() to mimic MS-DOS's dir
  85  *
  86  *    01/28/97 (Tim Norman)
  87  *        cleaned up Aaron's DIR code
  88  *
  89  *    06/13/97 (Tim Norman)
  90  *        moved DIR code to dir.c
  91  *        re-implemented Aaron's DIR code
  92  *
  93  *    06/14/97 (Steffan Kaiser)
  94  *        ctrl-break handling
  95  *        bug fixes
  96  *
  97  *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
  98  *        added config.h include
  99  *
 100  *    03-Dec-1998 (Eric Kohl)
 101  *        Replaced DOS calls by Win32 calls.
 102  *
 103  *    08-Dec-1998 (Eric Kohl)
 104  *        Added help texts ("/?").
 105  *
 106  *    18-Dec-1998 (Eric Kohl)
 107  *        Added support for quoted arguments (cd "program files").
 108  *
 109  *    07-Jan-1999 (Eric Kohl)
 110  *        Clean up.
 111  *
 112  *    26-Jan-1999 (Eric Kohl)
 113  *        Replaced remaining CRT io functions by Win32 io functions.
 114  *        Unicode safe!
 115  *
 116  *    30-Jan-1999 (Eric Kohl)
 117  *        Added "cd -" feature. Changes to the previous directory.
 118  *
 119  *    15-Mar-1999 (Eric Kohl)
 120  *        Fixed bug in "cd -" feature. If the previous directory was a root
 121  *        directory, it was ignored.
 122  *
 123  *    23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
 124  *        Improved chdir/cd command.
 125  *
 126  *    02-Apr-2004 (Magnus Olsen <magnus@greatlord.com>)
 127  *        Remove all hard code string so they can be
 128  *                translate to other langues.
 129  *
 130  *    19-Jul-2005 (Brandon Turner <turnerb7@msu.edu>)
 131  *        Rewrite the CD, it working as Windows 2000 CMD
 132  *
 133  *    19-Jul-2005 (Magnus Olsen <magnus@greatlord.com>)
 134  *        Add SetRootPath and GetRootPath
 135  *
 136  *    14-Jul-2007 (Pierre Schweitzer <heis_spiter@hotmail.com>)
 137  *        Added commands help display to help command (ex. : "help cmd")
