=head1 NAME

Socialtext::WikiObject - Represent wiki markup as a data structure and object

=cut

our $VERSION = '0.03';

=head1 SYNOPSIS

  use Socialtext::WikiObject;
  my $page = Socialtext::WikiObject->new(
                rester => $Socialtext_Rester,
                page => $wiki_page_name,
             );

=head1 DESCRIPTION

Socialtext::WikiObject is a package that attempts to fetch and parse some wiki
text into a perl data structure.  This makes it easier for tools to access
information stored on the wiki.

The goal of Socialtext::WikiObject is to create a structure that is 'good
enough' for most cases.

The wiki data is parsed into a data structure intended for easy access to the
data.  Headings, lists and text are supported.  Simple tables without multi-line
rows are parsed.

Subclass Socialtext::WikiObject to create a custom module for your data.  You
can provide accessors into the parsed wiki data.  

Subclasses can simply provide accessors into the data they wish to expose.

=head1 FUNCTIONS

=head2 new( %opts )

Create a new wiki object.  Options:

=over 4

=item rester

Users must provide a Socialtext::Resting object setup to use the desired 
workspace and server.

=item page

If the page is given, it will be loaded immediately.

   return $self;
}

=head2 load_page( $page_name )

Load the specified page.  Will fetch the wiki page and parse
it into a perl data structure.
