=head1 NAME

Mojolicious::Plugin::CoverDb - Mojolicious Plugin

=head1 SYNOPSIS

  # Mojolicious
  $self->plugin('CoverDb');
  $self->plugin('CoverDb' => { dir => 'cover_db', route => 'coverdb' });

  # Mojolicious::Lite
  plugin 'CoverDb';
  plugin 'CoverDb' => { dir => 'cover_db', route => 'coverdb' };

=head1 DESCRIPTION

L<Mojolicious::Plugin::CoverDb> is a L<Mojolicious> plugin to conveniently expose a C<cover_db> directory
generated by L<Devel::Cover>. You automatically get C<coverage.html> when going to the exposed route (if
the file exists, otherwise, you’get a list of the files).

As L<Devel::Cover> is a development tool, the directory is only exposed if C<MOJO_MODE> is C<development>.

=head1 OPTIONS

L<Mojolicious::Plugin::StaticCache> supports the following options.

=head2 dir

The directory to expose. It may be an absolute path or a path relative to your mojolicious app’s directory.

Default is C<cover_db>.

=head2 route

The route to the exposed directory.

Default is C<coverdb>.

=head1 METHODS

L<Mojolicious::Plugin::CoverDb> inherits all methods from
L<Mojolicious::Plugin> and implements the following new ones.

=head2 register

  $plugin->register(Mojolicious->new);

Register plugin in L<Mojolicious> application.
