At the moment I'm using
git cvsimport -C $DIR/git/gnuplot.git -p x -d $DIR/cvs/gnuplot gnuplot
to get gnuplot out of CVS repository.
So far this worked reliably, the only problems that I experienced were:
- I forgot the --delete switch when using rsync to fetch files from
CVS repository, so files were not removed from repository, but that
was entirely my fault
- I once deleted a directory in CVS which had disastrous consequences
since all the files from that directory are lost. But I think that
this is a limitation of CVS, not limitation of git import tool. Nobody
could restore those files. I had the git repository from an earlier
attempt, so this was not a problem, but the CVS repository is still of
questionable value.
- files in CVS repositories on sourceforge have utterly weird
permissions (like 575 for example); when I do "git cvsimport" those
permissions stay on files on the same computer, but since git doesn't
keep exact permissions, it turns out to be ok at the end
- Warning: commit message does not conform to UTF-8.
You may want to amend it after fixing the message, or set the config
variable i18n.commitencoding to the encoding your project uses.
Apart from that, no negative experience.

Sadly not. If I put their code to GitHub, this doesn't mean that
GitHub will become their primary version control system. I would use
it just to simplify packaging of ConTeXt distribution. However:
- it would be a convenient place for pgf developers to see which
patches are needed
- patches would be tested by ConTeXt users
- it would be much easier to keep track of changes that are needed
- we could use the bug tracker to keep track of changes that are still needed
- Aditya or anyone else would be free to play with more ConTeXt-like
code; pgf developers are not all aware of modern coding style in
ConTeXt, but if they received a ready solution, they might accept it
I have now put the files to
https://github.com/mojca/pgf
The location is temporary, so don't rely on it.
Here is what I did:
rsync -aO --delete rsync://pgf.cvs.sourceforge.net/cvsroot/pgf/ cvs/pgf
git cvsimport -C $PWD/git/pgf.git -p x -d $PWD/cvs/pgf pgf
git remote add origin g...@github.com:mojca/pgf.git
git push -u origin master
git push --tags
The main problem is that I'm not yet sure how to transform this into
TDS (keeping all the history etc.)
