 * Plugin Name:       Borrowdesk – Equipment Lending, Check-Out & Due Dates
 * Description:       Lend WP Inventory items to people: check out, due dates, returns, who has what, and overdue reminders.
 * Version:           0.4.2
 * Requires at least: 6.4
 * Requires PHP:      7.4
 * Author:            WP Inventory Manager
 * Author URI:        https://www.wpinventory.com/
 * License:           GPLv2 or later
 * License URI:       https://www.gnu.org/licenses/gpl-2.0.html
 * Text Domain:       borrowdesk
 *
 * No "Requires Plugins" header on purpose: WP Inventory Pro installs in its own folder
 * (wp-inventory-manager-pro), so a dependency on the free slug would refuse to activate on
 * every Pro site. See docs/standalone-plugins/foundations.md §2 in the meta repo.
