title: What's the eclipse preferences file format? Can I delete arbitrary lines in prefs.epf?
body: <p>I'm using knime, an eclipse product.  After having exported the eclipse preferences, I want to keep only some essential settings for system tests.</p>
  
  <p>But when I delete some lines in my preferences.epf file, it seems that it won't get re-imported correctly by eclipse/knime.</p>
  
  <p>At the first glance, the epf file format seems like a plain ini file without any hierarchical structure, is this correct?  Is there any epf format specification?</p>
  
  <p>Thanks for any help!</p>
