This is a simple plugin to the IRC bouncer ZNC. When connecting to ZNC through multiple clients it is not possible to use auto away functionality on one of them. This is because ZNC will pass through the /away [<reason>] command to the server. That means a client with auto away functionality that's idle will constantly send away commands even when other clients are in active use.

This plugin makes /away [<reason>] work on a per client basis. This means all connected clients need to be marked as away before the away command is sent to the server.

Use znc-buildmod on clientaway.cpp, follow the instructions on the ZNC Wiki. If you don't have the znc-buildmod command you probably need to install the znc-dev/znc-devel package from your distribution. You need at least ZNC version 1.7.0 to run this plugin.
