As some have already noticed, I created a c++-modules branch yesterday. 
Don't get too excited, that doesn't mean I have an implementation to 
commit there.

I expect several false starts, and don't intend to post patches here.

Wiki page is https://gcc.gnu.org/wiki/cxx-modules

Are you planning to add this to svn.html (where we generally
describe all branches)?

Ah, thanks for the reminder.

First, here's a patch to collate the existing list, ok?

(It seems quite a few may be dead now, time for some pruning?)

Oh, definitely.  This makes sense, and I trust your sorting
skills. :-)

You mean, moving them to "Inactive Development Branches"?  Yes,
that makes sense.  

(In fact, it might make sense to differentiate between "Merged 
Branches" and "Inactive Development Branches", but that may be
too much effort.)
