I don't want to violate anyone's privacy, but would it be proper to ask the email address of the programmer who wrote the www.tmac code? I have some questions (and not an avalanche of them) which I'm afraid no one else can answer. I've never been especially good at git (personal prejudice I have no intention of going into here) so if anyone could look into your archive and give me that email address (someone at gnu.org?) I'd appreciate that, or even just forwarding this mail to them, maybe that'd be enough.
Thanks.
