NAME
    Mac::Macbinary - Decodes Macbinary files.

SYNOPSIS
      use Mac::Macbinary;

      $mb = new Mac::Macbinary(\*FH);       # filehandle
      $mb = new Mac::Macbinary($fh);        # IO::* instance
      $mb = new Mac::Macbinary("/path/to/file");

      $header = $mb->header;                # Mac::Macbinary::Header instance
      $name = $header->name;

DESCRIPTION
    This module provides an object-oriented way to extract various kinds of
    information from Macintosh Macbinary files.

METHODS
    Following methods are available.

  Class method

    new(*THINGY*)
        Constructor of Mac::Macbinary. Accepts filhandle GLOB reference,
        FileHandle instance, IO::* instance, or whatever objects that can do
        `read' methods.

        If the argument belongs none of those above, `new()' treats it as a
        path to file. Any of following examples are valid constructors.

          open FH, "path/to/file";
          $mb = new Mac::Macbinary(\*FH);

          $fh = new FileHandle "path/to/file";
          $mb = new Mac::Macbinary($fh);

          $io = new IO::File "path/to/file";
          $mb = new Mac::Macbinary($io);

          $mb = new Mac::Macbinary "path/to/file";

        `new()' throws an exception "Can't read blahblah" if the given
        argument to the constructor is neither a valid filehandle nor an
        existing file.

  Instance Method

    data
        returns the data range of original file.

    header
        returns the header object (instance of Mac::Macbinary::Header).

    Following accessors are available via Mac::Macbinary instance.

    name, type, creator, flags, location, dflen, rflen, cdate, mdate
        returns the original entry in the header of Macbinary file. Below is
        a structure of the info file, taken from MacBin.C

          char zero1;
          char nlen;
          char name[63];
          char type[4];           65      0101
          char creator[4];        69
          char flags;             73
          char zero2;             74      0112
          char location[6];       80
          char protected;         81      0121
          char zero3;             82      0122
          char dflen[4];
          char rflen[4];
          char cdate[4];
          char mdate[4];

EXAMPLE
    Some versions of MSIE for Macintosh sends their local files as Macbinary
    format via forms. You can decode them in a following way:

      use CGI;
      use Mac::Macbinary;

      $q = new CGI;
      $filename = $q->param('uploaded_file');
      $type = $q->uploadInfo($filename)->{'Content-Type'};
     
      if ($type eq 'application/x-macbinary') {
          $mb = Mac::Macbinary->new($q->upload('uploaded_file');
          # now, you can get data via $mb->data;
      } 

TODO
    should add `is_macbinary()', to detect if a file is a Macbinary file or
    not.

    There are also `Mac::Conversions' and `Convert::BinHex', which works kind
    similar to this module. (However, `Mac::Conversions' works only on
    MacPerl, and `Convert::BinHex' is now deprecated.) Many thanks to Paul J.
    Schinder and Eryq, authors of those ones.
