Basic Navigation Commands
  The first thing to learn is the commands that allow you to navigate
  in the mudlib.  _Most_ of the commands are based on the unix commands
  of the same name, but will not include all the functionality that the
  unix ones do.
  The mudlib is comprised of a hierarchical set of directories starting
  from / (for those of you familiar with DOS this is the same concept).
                                 /
    __________________________________________________________
   |    |     |    |     |     |      |     |     |   |      |
  WWW admin arch areas cmds daemons data domains ftp help include ....
  The above are some of the very top level directories that comprise
  the mudlib on Islands of Myth.  Each of these directories have files, and
  other directories under them.
  pwd = present working directory.  This command shows you 2 things, 
        first it shows you the current directory your in, and it shows 
        you the last file you editted.
        >pwd
        Dir:  /
        File: /wiz/zenia/test/test_room1.c
  
        Looking at see that the directory I am currently in is /
        and that the last file i editted was /wiz/zenia/test/test_room1.c
  ls  = This command shows you the contents of the current directory, or
        the contents of the directory that you specify.  We also have a 
        corresponding dir command for those DOS users that cannot remember
        ls.
        The below example is an ls of the / directory.
        Those of you that are familiar with unix will notice that the
        default behavior of ls is as if ls -aF was typed.
               
        >ls
        /:
        .CHANGES     areas/       domains/     log/        
        WWW/         cmds/        ftp/         obj/        
        admin/       daemons/     help/        olddomains/ 
        arch/        data/        include/     oldwiz/     
        The names with the trailing / are directories.
        
  
        The below example shows how to see a directory besides the current
        one.  This example shows the contents of the /cmds directory.
        >ls /cmds
        /cmds/:
        README    ghost/         player/        race/          wiz/           
        frog/     p.c            points.c       verbs/         wiztest/  
        There is also a -l flag that can be used with ls to show file sizes
        and timestamps of particular files.
        >ls -l

  cd  = Change directory.  This command allows you to change your current
        directory. This works exactly as it does in DOS and unix.  Keep in 
        mind that there are some special characters that can be done with
        cd, and cd by itself takes you to your home directory.
  
        Special characters:
        .  =  current directory
        .. =  parent directory
         / =  root directory
        ~  =  your home directory
        
       Examples:
        >pwd
        Dir:  /wiz/zifnab
        File: /wiz/zenia/test/test_room1.c
 
        > cd /
        new pwd: /
         
        After doing this my current directory is /
        > cd
         new pwd: /wiz/zifnab
         cd by itself takes me to my directory.
      
        > cd ..
        new pwd: /wiz
        This took me up one level to /wiz
        > cd ~
        new pwd: /wiz/zifnab
        
        This took me to my directory.  Note that that is the same
        as cd by itself.
        > cd ~pavilion
        new pwd: /wiz/pavilion
        This took me to Pavilion's directory.
