/**
 * Plugin Name: Custom Content Portfolio
 * Plugin URI:  https://themehybrid.com/plugins/custom-content-portfolio
 * Description: Portfolio manager for WordPress.  This plugin allows you to manage, edit, and create new portfolio items in an unlimited number of portfolios.
 * Version:     2.1.0
 * Author:      Justin Tadlock
 * Author URI:  https://themehybrid.com
 * Text Domain: custom-content-portfolio
 * Domain Path: /lang
 *
 * The Custom Content Portfolio plugin was created to solve the problem of theme developers continuing
 * to incorrectly add custom post types to handle portfolios within their themes.  This plugin allows
 * any theme developer to build a "portfolio" theme without having to code the functionality.  This
 * gives more time for design and makes users happy because their data isn't lost when they switch to
 * a new theme.  Oh, and, this plugin lets creative folk put together a portfolio of their work on
 * their site.
