title: Smart CVS and Core data
body: <p>I have a smart cvs installed on my iMac, and i have update the application from the cvs.
  Then i did some changes on my code and on the core data ( core data changes are: remove some attributes from core data entity), then i tried to commit the changes to cvs, BUT i get the following error:</p>
  
  <p>Up-to-date check failed for `xxxxxxx.m' , (i.e xxxxxxx is the file name).
  command aborted.</p>
  
  <p>What do you think about this error? how to solve it, and get the successful commit ?</p>
