/*The ~/Registry.CC file is CosmiC code.
You can execute a tree branch of it.  The System
branch is executed in the System task boot phase.
Normally, you will place var declarations
in the branch you make, but since an arthmetic expression
is valid in CosmiC you can place simple expressions
without vars.
