Hello all,

I have been working on a tool that strips Files-Excluded from orig tarballs, like mk-origtargz does. Preliminary testing shows that it’s some 250x faster than mk-origtargz. This week I am going to work on that tool in the background while I get back to work on the rustc 1.83 → NN backport. (Previously mk-origtargz was so slow that I couldn’t get any backporting work done)
