I was thinking that it's good enough to convert the information recorded
by cvs. But it's certainly possible to add specified author names for
certain commits, as a part of the conversion process. The
config/Pike-real-authors file (from the
git://pike-git.lysator.liu.se/pcvs2git.git repository) is an example of
what that input file should look like. Since I haven't used it I'm not
sure how it works, but I could try to find out.

But it's going to be some manual work, going through the ChangeLog files
looking for contributed changes, and then looking at the cvs log to
identify affected revisions and writing the input file for
--contributors.

If you want to give it a try, I'll explain what's needed.

1. Get pike 7.8 release 550 or later, 
   http://pike.ida.liu.se/pub/pike/beta/7.8.550/Pike-v7.8.550.tar.gz

   Annoyingly enough, it doesn't support the most recent version of
   nettle, resulting in compilation errors on the DES glue. I had to #if
   out the DES and DES3 ciphers from the Nettle module. Alternatively,
   there should be some configure argument to force Pike to build with
   the bundled version of nettle, rather than the installed version.

2. Get git://pike-git.lysator.liu.se/pcvs2git.git. This includes
   Henrik's configuration file in config/lsh.pcvs2git.

3. Get the CVS repository. I'm putting a copy at
   http://www.lysator.liu.se/~nisse/misc/lsh-cvsroot.tar.gz

4. Create an authors.txt file, containing

nisse=Niels Möller <ni...@lysator.liu.se>
uid444=Niels Möller <ni...@lysator.liu.se>
_cvs_pont=Pontus Freyhult <p...@soua.net>

5. To do the conversion, I used the command line

   pike ../pcvs2git/pcvs2git.pike -c ../pcvs2git/config/lsh.pcvs2git \
    -A authors.txt -k -l -C lsh.git -d lsh-cvsroot/lsh

   It spawns a git fast-import process which populates the new
   repository.

The result should be almost identical to the current "test-2" repository
(Henrik has committed some tweaks for the generated .gitattributes
files).

To use a contributors file, add --contributors contributors.txt early
on the above command line (the -d option and argument has to come after
other options).

Regards,
/Niels
