Hi Philippe,

thanks for your detailed answer!

Yes, separate repositories might also make sense, I don't know what's better.
Having both in one repository (for now), would also allow to see a combined 
commit history.
And once everything is git, we can move/rename folders without losing that 
But if those two modules are completely separate and we never want to share 
code between, then two repositories are more suited.

My commands for cvs2git:
rsync -av rsync://cvs.savannah.gnu.org/sources/gnubg .
cvs2git --blobfile=./git-blob.dat --dumpfile=./git-dump.dat --keep-cvsignore 
--retain-conflicting-attic-files --encoding=ascii --encoding=utf8 
--encoding=utf16 --fallback-encoding=utf8 ./gnubg
mdkir gnubg-cvs2git && cd gnubg-cvs2git && git init
cat ../git-blob.dat ../git-dump.dat | git fast-import

I'm not sure I understand you correctly. Once using git, we would use full name 
/ email address anyway. This discussion is only about the commit history until 
now, not the future git commits.

That was poor wording on my side. With "first" I meant this should be done 
before my other suggestions are tackled, like refactoring of the code base. 
Renaming of files is much better handled in git than in CVS, the history and 
"git blame" can deal with that.

I completely agree with you that first we need a proper export to git and 
should give it enough time until we are certain of it.

Another detail: when I took another look at the two exports I did, I noticed a 
different number of commits (7285 vs 7532)
The reason is that sometimes one commit in cvs2git is two when using 

cvs2git also omits the CVS comments like
 * $Id: matchequity.c,v 1.106 2022/02/19 21:52:48 plm Exp $
We don't need them anymore, so that should be ok.

Personally I would skip the step via savannah. But yes, moving a git repository 
from savannah to somewhere else is very simple, quick and wouldn't change 
commit history.

I have only anecdotal data, but many people in HR hiring software engineers ask 
for your GitHub handle.
Even when applicants are not asked, I have seen many of them giving the URL to 
their account in their CV.
It's not only about numbers, it's also an easy way to check the quality of 
those contributions.
And yes, some people also inflate those numbers and brag about it, just check
Maybe we should stop discussing contribution statistics here, but for gnubg you 
would definitely win 2022 :)
