  <p>How you can see I have the one branch and 4 heads.
  When I try to pull in my eclipse mercurial plugin, it returns me message about multiple heads and offers me to rebase or merge. Then I did not understand anything and closed it.
  I think I need something to delete this heads. It would be great if somebody could explain me this and show how to do this in the eclipse plugin, but other help is appreciated.</p>
