title: Post-build step in Eclipse CDT
body: <p>Eclipse SDK 3.5.1, CDT.
  I have the following workspace tree:</p>
  
  <pre>
  Bin (just directory)
  --Debug
  --Release
  Client (project)
  --Debug
  --Release
  </pre>
  
  <p>In the Client project, Debug configuration, I fill Post-Build step:</p>
  
  <pre>
  cp Debug/Client ../Bin/Debug/
  </pre>
  
  <p>I want to copy output executable to Bin/Debug directory.
  Building the project, I have this error message:
  make[1]:[post-bulld] Error 1 (ignored) line 0</p>
  
  <p>What is wrong?
  Also, can I use some variables, like Workspace directory, current configuration etc. in Post-Build step? Where can I find these variables and how to use them?
  Thank you.</p>
