=head1 NAME

Dist::Zilla::Plugin::Git::Check - Check your git repository before releasing

=head1 VERSION

version 2.046

=head1 SYNOPSIS

In your F<dist.ini>:

    [Git::Check]
    allow_dirty = dist.ini
    allow_dirty = README
    changelog = Changes      ; this is the default
    build_warnings = 0       ; this is the default
    untracked_files = die    ; default value (can also be "warn" or "ignore")

=head1 DESCRIPTION

This plugin checks that your Git repo is in a clean state before releasing.
The following checks are performed before releasing:

=over 4

=item * there should be no files in the index (staged copy)

=item * there should be no untracked files in the working copy

=item * the working copy should be clean. The files listed in
C<allow_dirty> can be modified locally, though.

=back

If those conditions are not met, the plugin will die, and the release
will thus be aborted. This lets you fix the problems before continuing.

The plugin accepts the following options:

=over 4

=item * changelog - the name of your changelog file. defaults to F<Changes>.

=item * allow_dirty - a file that is allowed to have local
modifications.  This option may appear multiple times.  The default
list is F<dist.ini> and the changelog file given by C<changelog>.  You
can use C<allow_dirty => to prohibit all local modifications.

=item * allow_dirty_match - works the same as allow_dirty, but
matching as a regular expression instead of an exact filename.

=item * build_warnings - if 1, perform the same checks after every build,
but as warnings, not errors.  Defaults to 0.

=item * untracked_files - indicates what to do if there are untracked
files.  Must be either C<die> (the default), C<warn>, or C<ignore>.
C<warn> lists the untracked files, while C<ignore> only prints the
total number of untracked files.
