title: Turning Proguard On/Off Using Properties
body: <p>In my project.properties file there is a property proguard.config and when i run ant it will run proguard.  All of the following will cause proguard to run</p>
  
  <pre><code> proguard.config
   proguard.config=
   proguard.config=proguard.cfg
  </code></pre>
  
  <p>Is there a way within the properties file to turn proguard on/off?</p>
  
  <p>Otherwise I am going to need to write a script to add/remove or rename the proguard.config property to control this.  I would rather just get/set properties.  I want the best solution for this.  Right now I am coding replaceregexpr to rename the proguard.config to something else to turn off. Looking for a better solution and would like to know how others are controlling this?</p>
