Import nant version 0.86beta1.

NAnt is a free .NET build tool. In theory it is kind of like make without
make's wrinkles. In practice it's a lot like Ant.

NAnt is different.  Instead of a model where it is extended with shell-based
commands, NAnt is extended using task classes.  Instead of writing shell
commands, the configuration files are XML-based, calling out a target tree
where various tasks get executed.  Each task is run by an object that
implements a particular Task interface.
