OVERVIEW

12       The Nester transformer is meant to find potential container elements
13       and make them into actual containers.  It works by being told what
14       elements may be made into containers and what subsequent elements they
15       should allow to be stuffed into them.
16
17       For example, given the following nester:
18
19         use Pod::Elemental::Selectors qw(s_command s_flat);
20
21         my $nester = Pod::Elemental::Transformer::Nester->new({
22           top_selector      => s_command('head1'),
23           content_selectors => [
24             s_command([ qw(head2 head3 head4) ]),
25             s_flat,
26           ],
27         });
28
29       ..then when we apply the transformation:
30
31         $nester->transform_node($document);
32
33       ...the nester will find all "=head1" elements in the top-level of the
34       document.  It will ensure that they are represented by objects that
35       perform the Pod::Elemental::Node role, and then it will move all
36       subsequent elements matching the "content_selectors" into the
37       container.
38
39       So, if we start with this input:
40
41         =head1 Header
42         =head2 Subheader
43         Pod5::Ordinary <some content>
44         =head1 New Header
45
46       The nester will convert its structure to look like this:
47
48         =head1 Header
49           =head2 Subheader
50           Pod5::Ordinary <some content>
51         =head1 New Header
52
53       Once an element is reached that does not pass the content selectors,
54       the nesting ceases until the next potential container.
55

ATTRIBUTES

57   top_selector
58       This attribute must be a coderef (presumably made from
59       Pod::Elemental::Selectors) that will test elements in the transformed
60       node and return true if the element is a potential new container.
61
62   content_selectors
63       This attribute must be an arrayref of coderefs (again presumably made
64       from Pod::Elemental::Selectors) that will test whether paragraphs
65       subsequent to the top-level container may be moved under the container.
