NAME
    Tie::HashArray - Allows arays to be stored inside a hash.

SYNOPSIS
      use Tie::CmplxHash;
      tie %newhash, \%oldhash [, CACHE_SIZE]; # Create the new hash object.
      $newhash{key} = $arrayref; # Store the array into the hash.
      $arrayref = $newhash{key}; # Get the array from the hash.

REQUIRES
    Perl 5.004, Storable, Carp

DESCRIPTION
    This module uses the Storable module to serialize/deserialize
    data and store/fetch it from the original hash.

    All operations are performed on references. This means that the
    original hash can be any hash (DBM, regular hash or even another
    Tie module). It also means that it can store not only arrays but
    anything you want (though if you need to store anything much
    more complex than an array I sugest finding a better solution).

    The main intent for this module is to store more complex data
    structures into DBM files. DBM's are wonderful for small to
    medium amounts of data. But when complex data structures are
    needed it can get hairy. And there are times when a RDBMS is
    just a little much. So this module extends the middle ground
    that DBM files cover just a little bit more.

CACHE
    Yes you heard me right, cache. I have implemented a small, no
    frills, cache to speed things up a little. When working with
    large data structures or just a lot of data things can get a
    little slow. So if CACH_SIZE is specified caching is turned on
    and the last CACHE_SIZE keys that are accessed are kept in
    memory.

    All that is actually stored is te reference. This will keep
    Perls garbage collector from freeing that memory (at least I
    hope it alwayse works that way) so it stays available.

    When deciding wether to use cachin or not keep in mind that
    caching can actually do more harm than good. It all depends on
    how you use the data. If you do more reads than writes caching
    may help. But if you do more writes than reads it will
    definitely harm you. Play with CACHE_SIZE and see what results
    you get.

WARNING
    DO NOT MODIFY THE ORIGINAL HASH. Unless you know what you are
    doing, once you start using this module on a hash DO NOT touch
    it directly. In fact only use this module on a brand new fresh
    hash. All kinds of nasty stuff could occure. Stuff that I don't
    know how or fell like checking for. This is not a end all do all
    module, it is a tool. If used properly it can help out a lot,
    just like any other tool. And if use improperly it can cause BIG
    headaches, just like any other tool.

    As mentioned in the code and below. There is no waranty at all.
    I am not responsable for what you do with this tool. If
    important data is destroyed it's your problem, not mine. I
    warned you.

INSTALLATION
    The same as all CPAN modules.

    perl Makefile.PL
