RE: If RCS can stand it, why can't your system?

*I thought* he was saying it's not good for a community/tool when people develop exporters that take dumps from their system and use it to write importers into competing tools (eg GIT) without providing the reverse.

What he thinks we should be doing is writing *importers* for our tool, to take git dumps and import them to SVN. The problem is that it is now easy to migrate from SVN to git, but it's not so easy to migrate from git to SVN.

I guess this state of play is quite normal - new stuff always has people willing to write tools to support it. I wrote a VSS to SVN importer, because I needed one, but no-one really needs a git to SVN importer as git is the new kid. Maybe one day they'll see the need to migrate from git, and someone will then write the tool to do that.

Perhaps Mr Raymond will put his money where his mouth is and write this git->svn tool if reposurgeon makes it so easy.

<stands back and waits for Eric to say "I'll bloody well show him", and write it> :)
