'''Overview'''

Basically Feather is simply a collection of C extensions to Tcl which 
provides a set of really useful Tcl commands. All of the extensions are 
Stub enabled (they both use Tcl's Stub interface and provide their own).
At the moment is it at version 0.1 because it has no documentation, no 
tests and no configuration and the C API and to a smaller extent the Tcl
API are not stabilised.

Feather requires Tcl8.0 or later with Stubs support.
