Description-en: System tray for KDE3/GNOME2 docklet applications
Docker is a docking application (WindowMaker dock app) which acts as a system
tray for any desktop environment, allowing you to have a system tray without
running the KDE/GNOME panel Docker was designed to work with Openbox 2, but it
should work fine in any window manager.

Description : Docker is an open-source engine that automates the deployment of any
: application as a lightweight, portable, self-sufficient container that will
: run virtually anywhere.
:
: Docker containers can encapsulate any payload, and will run consistently on
: and between virtually any server. The same container that a developer builds
: and tests on a laptop will run at scale, in production*, on VMs, bare-metal
: servers, OpenStack clusters, public instances, or combinations of the above.
