=head1 NAME

Pod::Weaver::PluginBundle::Author::ETHER - A plugin bundle for pod woven by ETHER

=head1 VERSION

version 0.173

=head1 SYNOPSIS

In your F<weaver.ini>:

    [@Author::ETHER]

Or in your F<dist.ini>

    [PodWeaver]
    config_plugin = @Author::ETHER

It is also used automatically when your F<dist.ini> contains:

    [@Author::ETHER]
    :version = 0.094    ; or any higher version

=head1 DESCRIPTION

=for stopwords optimizations GenerateSection

=for Pod::Coverage configure mvp_bundle_config

This is a L<Pod::Weaver> plugin bundle. It is I<approximately> equal to the
following F<weaver.ini>, minus some optimizations:

    [-EnsurePod5]
    [-H1Nester]
    [-SingleEncoding]

    [-Transformer / List]
    transformer = List

    [-Transformer / Verbatim]
    transformer = Verbatim

    [Region / header]
    [Name]
    [Version]

    [Region / prelude]

    [Generic / SYNOPSIS]
    [Generic / DESCRIPTION]
    [Generic / OVERVIEW]

    [Collect / ATTRIBUTES]
    command = attr

    [Collect / METHODS]
    command = method

    [Collect / FUNCTIONS]
    command = func

    [Collect / TYPES]
    command = type

    [Leftovers]

    [Region / postlude]

    [GenerateSection / generate GIVING THANKS]
    title = GIVING THANkS
    main_module_only = 0
    text = <template>

    [GenerateSection / generate SUPPORT]
    title = SUPPORT
    main_module_only = 0
    text = <template>

    [Authors]
    [AllowOverride / allow override AUTHOR]
    header_re = ^AUTHORS?\b
    action = replace
    match_anywhere = 0

    [Contributors]
    :version = 0.008

    [Legal]
    :version = 4.011
    header = COPYRIGHT AND <licence filename>

    [Region / footer]

This is also equivalent (other than section ordering) to:

    [-Transformer / List]
    transformer = List
    [-Transformer / Verbatim]
    transformer = Verbatim

    [Region / header]
    [@Default]

    [Collect / TYPES]
    command = type

    [GenerateSection / generate GIVING THANKS]
    title = GIVING THANKS
    main_module_only = 0
    text = <template>

    [GenerateSection / generate SUPPORT]
    title = SUPPORT
    main_module_only = 0
    text = <template>

    [Authors]
    [Contributors]
    :version = 0.008

    [Region / footer]

=head1 OPTIONS

None at this time. (The bundle is never instantiated, so this doesn't seem to
be possible without updates to L<Pod::Weaver>.)

=head1 OVERRIDING A SPECIFIC SECTION

This F<weaver.ini> will let you use a custom C<COPYRIGHT AND LICENCE> section and still use the plugin bundle:

    [@Author::ETHER]
    [AllowOverride / OverrideLegal]
    header_re = ^COPYRIGHT
    match_anywhere = 1
    action = append

=head1 ADDING STOPWORDS FOR SPELLING TESTS

As noted in L<Dist::Zilla::PluginBundle::Author::ETHER>, stopwords for
spelling tests can be added by adding a directive to pod:

    =for stopwords foo bar baz

However, if the stopword appears in the module's abstract, it is moved to the
C<NAME> section, which will be above your stopword directive. You can handle
this by declaring the stopword in the special C<header> section, which will be
woven ahead of everything else:

    =for :header
    =for stopwords foo bar baz
