=head2 $file_parser->parse_paras(\@paras, $message)

Parse the paragraphs paras. Paras can either be strings, in which case
they'll be considered plain texts. Or they can be hash refs with the key
're' pointing to a regex string.

Here's an example:

    my @synopsis_paras = (
        '=head1 SYNOPSIS',
        'Quick summary of what the module does.',
        'Perhaps a little code snippet.',

        { re => q{\s*} .
            quotemeta(q{my $foo = MyModule::Test->new();})
            . q{\n\s*} . quotemeta("..."), },
    );

    $mod1->parse_paras(
        \@synopsis_paras,
        'MyModule::Test - SYNOPSIS',
    );

        map { (ref($_) eq 'HASH') ? $_->{re} : quotemeta($_) }
