Hi,It seems the current man page (the one provided upstream along with the code source) still is outdated.
i.e: `peer_exchange` isn't valid and has been replaced by protocol.pex
I haven't checked thoroughly, but the community has written this: https://rtorrent-docs.readthedocs.io/en/latest/ and the Github wiki pages also contain some documentation. So I guess the man page is doomed.
