1.1.1.1

@Initial import of Kyua CLI, version 0.6:

This is the main component of Kyua and its build will be guarded by the
MKKYUA knob.  core@@ has approved this import.

Description:

Kyua (pronounced Q.A.) is a testing framework for both developers and
users.  Kyua is different from most other testing frameworks in that it
puts the end user experience before anything else.  There are multiple
reasons for users to run the tests themselves, and Kyua ensures that
they can do so in the most convenient way.

This module, kyua-cli, provides the command-line interface to the Kyua
runtime system.  The major purpose of this tool is to run test cases and
generate unified reports for their results.
