title: Tools to evaluate callgrind's call profiles?
body: <p>Somehow related to <a href="https://stackoverflow.com/questions/1771340/can-i-export-tables-from-kcachegrind">this question</a>, which tool would you recommend to evaluate the profiling data created with callgrind? </p>
  
  <p>It does not have to have a graphical interface, but it should prepare the results in a concise, clear and easy-to-interpret way. I know about e.g. <code>kcachegrind</code>, but this program is missing some features such as data export of the tables shown or simply copying lines from the display.</p>
