NAME
    CSS::Inliner - Library for converting CSS <style> blocks to inline
    styles.

SYNOPSIS
    use Inliner;

    my $inliner = new Inliner();

    $inliner->read_file({filename => 'myfile.html'});

    print $inliner->inlinify();

DESCRIPTION
    Library for converting CSS style blocks into inline styles in an HTML
    document. Specifically this is intended for the ease of generating HTML
    emails. This is useful as even in 2009 Gmail and Hotmail don't support
    top level <style> declarations.

CONSTRUCTOR
    new ([ OPTIONS ])
        Instantiates the Inliner object. Sets up class variables that are
        used during file parsing/processing. Possible options are:

        html_tree (optional). Pass in a custom instance of HTML::Treebuilder

        strip_attrs (optional). Remove all "id" and "class" attributes
        during inlining

        leave_style (optional). Leave style/link tags alone within <head>
        during inlining

METHODS
    fetch_file( params )
         Fetches a remote HTML file that supposedly contains both HTML and a
         style declaration. It subsequently calls the read() method
         automatically.

         This method expands all relative urls, as well as fully expands the
         stylesheet reference within the document.

         This method requires you to pass in a params hash that contains a
         url argument for the requested document. For example:

         $self->fetch_file({ url => 'http://www.example.com' });

    read_file( params )
         Opens and reads an HTML file that supposedly contains both HTML and
         a style declaration. It subsequently calls the read() method
         automatically.

         This method requires you to pass in a params hash that contains a
         filename argument. For example:

         $self->read_file({filename => 'myfile.html'});

    read( params )
         Reads html data and parses it. The intermediate data is stored in
         class variables.

         The <style> block is ripped out of the html here, and stored
         separately. Class/ID/Names used in the markup are left alone.

         This method requires you to pass in a params hash that contains
         scalar html data. For example:

         $self->read({html => $html});

    inlinify()
         Processes the html data that was entered through either 'read' or
         'read_file', returns a scalar that contains a composite chunk of
         html that has inline styles instead of a top level <style>
         declaration.

    query()
         Given a particular selector return back the applicable styles

    specificity()
         Given a particular selector return back the associated selectivity
