=head1 NAME

HTTP::Body - HTTP Body Parser

=head1 SYNOPSIS

    use HTTP::Body;
    
    sub handler : method {
        my ( $class, $r ) = @_;

        my $content_type   = $r->headers_in->get('Content-Type');
        my $content_length = $r->headers_in->get('Content-Length');
        
        my $body   = HTTP::Body->new( $content_type, $content_length );
        my $length = $content_length;

        while ( $length ) {

            $r->read( my $buffer, ( $length < 8192 ) ? $length : 8192 );

            $length -= length($buffer);
            
            $body->add($buffer);
        }
        
        my $uploads     = $body->upload;     # hashref
        my $params      = $body->param;      # hashref
        my $param_order = $body->param_order # arrayref
        my $body        = $body->body;       # IO::Handle
    }

=head1 DESCRIPTION

HTTP::Body parses chunks of HTTP POST data and supports 
application/octet-stream, application/x-www-form-urlencoded, and
multipart/form-data.

Chunked bodies are supported by not passing a length value to new().

It is currently used by L<Catalyst> to parse POST bodies.

=head1 NOTES

When parsing multipart bodies, temporary files are created to store any
uploaded files.  You must delete these temporary files yourself after
processing them, or set $body->cleanup(1) to automatically delete them
at DESTROY-time.

=head1 METHODS

=over 4 

=item new 

Constructor. Takes content type and content length as parameters,
returns a L<HTTP::Body> object.
