Whatpm::NanoDOM - A Non-Conforming Implementation of DOM Subset |
| 4 |
|

=head1 DESCRIPTION |
| 6 |
|
| 7 |
The C<Whatpm::NanoDOM> module contains a non-conforming implementation |
| 8 |
of a subset of DOM. It is the intention that this module is |
| 9 |
used only for the purpose of testing the C<Whatpm::HTML> module. |
| 10 |
|
| 11 |
See source code if you would like to know what it does. |
