title: mercurial hg and kdiff3
body: <p>I am in windows. I use Mercurial hg. I made a clone of a project (hg clone) then hg pull another project (hg pull). So mercurial asks me to do a merge of the two projects. And then there is a conflict between the two projects. And now I know what to do because kdiff3 does not open automatically so that I can resolve the conflict.</p>
  
  <p>So if someone had an idea of ​​how I could make kdiff3 opens automatically when mercurial encounter conflict.</p>
  
  <p>Thank you very much and good day.</p>
