       IO::Dir - supply object methods for directory handles

           use IO::Dir;
           $d = IO::Dir->new(".");
           if (defined $d) {
               while (defined($_ = $d->read)) { something($_); }
               while (defined($_ = $d->read)) { something_else($_); }
               undef $d;

           tie %dir, 'IO::Dir', ".";
           foreach (keys %dir) {
               print $_, " " , $dir{$_}->size,"\n";

       The "IO::Dir" package provides two interfaces to perl's directory
       reading routines.

       The first interface is an object approach. "IO::Dir" provides an object
       constructor and methods, which are just wrappers around perl's built in
       directory reading routines.

       new ( [ DIRNAME ] )
           "new" is the constructor for "IO::Dir" objects. It accepts one
           optional argument which,  if given, "new" will pass to "open"

       The following methods are wrappers for the directory related functions
       built into perl (the trailing `dir' has been removed from the names).
       See perlfunc for details of these functions.

       open ( DIRNAME )
       read ()
       seek ( POS )
       tell ()
       rewind ()
       close ()

       "IO::Dir" also provides an interface to reading directories via a tied
       hash. The tied hash extends the interface beyond just the directory
       reading routines by the use of "lstat", from the "File::stat" package,
       "unlink", "rmdir" and "utime".

       tie %hash, 'IO::Dir', DIRNAME [, OPTIONS ]

       The keys of the hash will be the names of the entries in the directory.
       Reading a value from the hash will be the result of calling
       "File::stat::lstat".  Deleting an element from the hash will delete the
       corresponding file or subdirectory, provided that "DIR_UNLINK" is
       included in the "OPTIONS".

       Assigning to an entry in the hash will cause the time stamps of the
       file to be modified. If the file does not exist then it will be
       created. Assigning a single integer to a hash element will cause both
       the access and modification times to be changed to that value.
       Alternatively a reference to an array of two values can be passed. The
       first array element will be used to set the access time and the second
       element will be used to set the modification time.
