/**
* @file mod/dfrn_confirm.php
* @brief Module: dfrn_confirm
* Purpose: Friendship acceptance for DFRN contacts
*.
* There are two possible entry points and three scenarios.
*.
* 1. A form was submitted by our user approving a friendship that originated elsewhere.
* This may also be called from dfrn_request to automatically approve a friendship.
*
* 2. We may be the target or other side of the conversation to scenario 1, and will
* interact with that process on our own user's behalf.
*.
* @see PDF with dfrn specs: https://github.com/friendica/friendica/blob/master/spec/dfrn2.pdf
* You also find a graphic which describes the confirmation process at
* https://github.com/friendica/friendica/blob/master/spec/dfrn2_contact_confirmation.png
