That works for me.

It's up to you whether the added complexity of the escaping logic is worth having - simply checking for '%' and bailing out would be sufficient. But since this works already...

If we have two digits in version numbers, it might make sense to move the logic into a Python script, or something similar. But we can worry about that later.

My concern is not so much with complex pipes, but with the difficulty in debugging them. As you have seen, the intermediate targets (such as some of the index.txt files) get cleaned up by make when things work, but if a step fails, the intermediate files are there for inspection. I really don't want to create more work for you now, but if we decide to extend this in the future, I would like to put some of the lists of targets into text files (rather than just keeping them in variables). For me, this would have helped pinpoint the exact origin of the "echo -e" problem.

Please don't take this as criticism, or a request to rewrite it now. I think the overall effect is excellent, and I am just pondering ways that might make it easier for others to help add new features in the future.

Thanks,
