=head1 NAME

WE_Frontend::Plugin::Teaser - teaser support

=head1 SYNOPSIS

From Template-Toolkit templates:

    [%- USE t = Teaser(objid=teaserpageid) -%]
    [%- SET teasercontent = t.content(teaser=teasernumber) -%]
    [%- FOREACH item = teasercontent.ct -%]
    ...
    [%- END -%]

=head1 DESCRIPTION

=over

=item Teaser(objid = pageid)

Construct a teaser object with the specified object id.

=item content(teaser = teaser, lang = language)

Return the content of a requested teaser (by teaser number).
Optionally use the specific language. If the C variable is not
given, then look for the C variable in the global Template
stash, otherwise fallback to C.
