No worries, I just wasn't sure if you saw that question in the midst
of the larger email.

Yeah, that can certainly wait for a later release.

Doesn't the <project> get substituted in config.install.* at
libbuild2/install/init.cxx:proc_var during the install module init? So
would the config.build actually persist the un-expanded variable or
the expanded variable?

I see. This also looks a bit weird since you don't have to escape the
'>' here, so it's asymmetric. I suppose you'd have to do an analogous
escape if '$' were used for the variable, but no need for the trailing
bracket.
