this program is meant to replace net/sendxmpp which is unmaintained and broken for most users (one person reported it worked for them but would be happy to switch to something maintained)
it's just a command line tool that takes a message in parameter or on stdin and send it to XMPP contacts/MUC. It's working well and maintained ok to import? Once done, I'll ask to remove net/sendxmpp and add a quirk entry to automatically upgrade net/sendxmpp to net/go-sendxmpp, and add a FAQ entry about this change because the configuration file format changed.
