Unstable: May Change Without Warning
This manual documents some of the libraries available in the unstable collection.
The name unstable is intended as a warning that the interfaces in particular are unstable. Developers of planet packages and external projects should avoid using modules in the unstable collection. Contracts may change, names may change or disappear, even entire modules may move or disappear without warning to the outside world.
Developers of unstable libraries must follow the guidelines in Guidelines for Developing unstable Libraries.
