title: Atmel Studio 7 command line build - define symbols on command line
body: <p>I am using the following command to build an atmel studio project on the command line:</p>
  
  <p><code>AtmelStudio.exe C:\blahblah\solution.atsln /rebuild DEBUG /project PROJNAME /out output.txt</code></p>
  
  <p>I would like to define symbols and override the values defined in the project's .cproj file, so that I do not need to define many different configurations. Is this possible, or do I need to use some other tool?</p>
