Can I split a Mercurial repository?

I have a largish Mercurial repository that I've decided would be better as several smaller repositories. Is there a way that I can split the repository and have each piece retain its revision history?

From stackoverflow

• Just clone it and delete the unwanted stuff out of each copy.

  Ry4an : That doesn't help. Every close still has full history, so the "too much stuff" will always be there in the ".hg" directory taking up space.

  Jason S : ah, you want the Stalinist revisionism form of version control. ;) http://en.wikipedia.org/wiki/Historical_revisionism_(negationism)

• The best way to do this is using the 'convert' extension. You'll use mercurial and both source and destination type and then use a --filemap with entries like:

  exclude path/you/do/not/want
  rename path/you/do/want .
  

  The rename is only necessary if you want to take the parts you're keeping and move them "higher" in the directory hierarchy.

  Nathan Lee : This wont work: rename path/you/do/want / This will: rename path/you/do/want . This only applies if you are moving a path to the root.

  Ry4an : Indeed, thanks, Nathan.
