ROLE-Prosody-compat.md

Prosody compatibility for ROLE SDK

1. Download latest nightly of prosody https://prosody.im/nightly/trunk/ or checkout trunk from hg http://prosody.im/source/start#checking_out_with_mercurial
2. apply patch in the prosody directory

  cd prosody
  patch -p1 < role.patch

3. edit prosody.cfg.lua and add

pubsub_capabilities = {
    none = {
        create = true;
        publish = true;
        retract = true;
    }
}
