xidlehook(-daemon)

This is the main xidlehook application. It's somewhat a subject of feature creep unfortunately, but that also makes it fairly flexible, enough for most people. Most contributions of xidlehook may should probably go here, unless it's in one of the standard modules or other core internals.

If you're dissatisfied with the API of xidlehook-daemon, think twice whether or not you really want to rely on this client or whether you want to unleash the full flexibility of the inner workings by making your own client for it, in the xidlehook-core repository.
