=head1 NAME

Dist::Zilla::Plugin::Git::Push - Push current branch

=head1 VERSION

version 2.048

=head1 SYNOPSIS

In your F<dist.ini>:

    [Git::Push]
    push_to = origin       ; this is the default
    push_to = origin HEAD:refs/heads/released ; also push to released branch
    remotes_must_exist = 1 ; this is the default

=head1 DESCRIPTION

Once the release is done, this plugin will push the current git branch to
the remote, with the associated tags.

The plugin accepts the following options:

=over 4

=item *

push_to - the name of the a remote to push to. The default is F<origin>.
This may be specified multiple times to push to multiple repositories.

=item *

remotes_must_exist - if true, then Git::Push checks before a release
to ensure that all named remotes specified in C<push_to> are
configured in your repo.  The default is true.  Remotes specified as a
URL or path are not checked, but will produce a
C<Will push to %s (not checked)> message.
