This is a meta-module that simply enables all the modules required to support Siskin or Snikket iOS on a Prosody server.
These are currently:
See the individual module pages for more details. In particular,
mod_cloud_notify_encrypted depends on luaossl,
which must be installed. It is available in Debian via apt as
luarocks install luaossl.
Note: On MUC services you should also load mod_muc_offline_delivery directly under the MUC component in your config file, that is not handled by this module.
There is no configuration for this module, just add it to modules_enabled as normal.
