  A .hgignore

  ? examples/SampleTestingSolution/EmptyGeneralTesting/SPA/Parser.h
  ? examples/SampleTestingSolution/EmptyGeneralTesting/UnitTesting/Debug/UnitTesting.write.1.tlog
  </code></pre>
  
  <p>So I made <code>.hgignore</code> look like</p>
  
  <pre><code>syntax: glob
  
  *.lib
  *.tlog
  *.log
  *.obj
  *.tlog
  *.idb
  *.pdb
  *.exe
  *.ilk
  *.filters
  </code></pre>
  
  <p>When I do hg status again, I see a similar/non noticeable difference in output. Why? I expected all those to be gone from <code>hg status</code></p>
