@hackage hub1.3.0

For multiplexing GHC installations and providing development sandboxes

This package provides a utility for multiplexing multiple GHC and Haskell Platform installations, the installation being selected by environment variable or a hidden configuraton file or in the current working directory or one of its parents.

Thye utility also allows users to build sandboxes (called hubs) which may link to one of the the GHC installtions installed on the local system, and extend them with packages private to the hub.

Utilities are also provided for erasing packages from an hub and annotating, duplicating, renaming, locking, archiving and recovering hubs.
