Nickolay - Task.Joose.Stable-3.05
Name
Task.Joose.Stable - Stable Joose distribution, required only for bootstraping purposes.
DESCRIPTION
Since Joose testing tool (Test.Run) is written in Joose itself, the "chicken and egg" problem arise.
Task.Joose.Stable is supposed to solve it. It just contain the version of Joose, which assumes to be "stable".
Some tools depends on this package instead of the main package - Joose.
