Usage

You can user any of above. All are same.

Just make sure you edit $repos.

<?php
$repos  = array(
    'bad-plugin' => array (
                'branch' => 'master',
                'localpath' => '/var/www/wcmum.rtcamp.net/htdocs/wp-content/plugins/bad-plugin'
                ),
    'other-plugin' => array (
                'branch' => 'master',
                'localpath' => '/var/www/wcmum.rtcamp.net/htdocs/wp-content/plugins/other-plugin'
                )

  );
?>

TODO

1. Add github secret support
2. Add base-path support for wordpress projects to avoid repeating /path/to/wp-content. With absolute/relative path check on localpath.
