That applies to all three of the tools changed. I forgot to propagate the last minute CTXLESS changes to the tools. And unfortunately we don't have test cases for the tools :-(. I've got a fix in my github branch that I will incorporate into v2. I'm also wondering if it would be preferable to replace the individual bias command line flags with a single bias parameter, e.g. --bias=pull-up I've coded that in my github branch as well, if you would care to compare. Let me know if you'd like a v2, otherwise I'll hold off for a few days in case something else crops up. Cheers, Kent.

They use the --bias/--drive forms as that is what is currently at the HEAD, but it is trivial to change them to the distinct flag versions if you prefer that.
