nashorn in type-annotations

[Werner Dietl]

I've cloned

http://hg.openjdk.java.net/type-annotations/type-annotations/nashorn

but cannot update it relative to http://hg.openjdk.java.net/jdk8/tl/nashorn.
I get this:

$ hg inco main
comparing with http://hg.openjdk.java.net/jdk8/tl/nashorn
searching for changes
abort: repository is unrelated

Is this a repo I should keep in sync between type-annotations and tl?
How can we make these repositories related?

Thanks,
cu, WMD.
