/*
This file handles the support licensing control for Paid Memberships Pro
and PMPro addons.
How it works:
- All source code and resource files bundled with this plugin are licensed under the GPLv2 license unless otherwise noted (e.g. included third-party libraries).
- An additional "support license" can be purchased at https://www.paidmembershipspro.com/pricing/
which will simultaneous support the development of this plugin and also give you access to support forums and documentation.
- Once your license has been purchased, visit Settings --> PMPro License in your WP dashboard to enter your license.
- Once the license is activated all "nags" will be disabled in the dashboard and member links will be added where appropriate.
- This plugin will function 100% even if the support license is not installed.
- If no support license is detected on this site, prompts will show in the admin to encourage you to purchase one.
- You can override these prompts by setting the PMPRO_LICENSE_NAG constant to false.
*/
