🍿 Send webmention via cURL

Snacks (🍿) are my collection of recipes for solving problems. Often recorded (and cleaned up) from actual discussions where I'm involved in helping others with technical problems. Not all solutions are mine but I started collecting them in one place because you never know when you need one.

1. Find the target's webmention endpoint with rel=webmention

2. curl -i -d source=source -d target=target endpoint
