Description:

The heart of the Meanwhile Project is the Meanwhile library, providing
the basic Lotus Sametime session functionality along with the core
services: Presence Awareness, Instant Messaging, Multi-user
Conferencing, Preferences Storage, Identity Resolution, and File
Transfer. This extensible client interface allows additional services
to be added to a session at runtime, allowing for simple integration
of future service handlers such as the user directory and whiteboard
and screen-sharing.
