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