title: java compiler options i.e. javac -d
body: <p>I'm compiling a program that has a package statement. 
  e.g.</p>
  
  <pre><code>package APPC_LU62.Runtime ;
  </code></pre>
  
  <p>I also have a pre-existing directory structure that matches the package statement.   </p>
  
  <pre><code>C:\APPC_LU62\Runtime
  </code></pre>
  
  <p>How do I keep the javac compiler from creating the same directory structure within the pre-existing one ? i.e.</p>
  
  <pre><code>C:\APPC_LU62\Runtime\APPC_LU62\Runtime   
  </code></pre>
  
  <p>It seems to me the compiler ought to be "smart" enough to check first for an existing directory structure before creating one.</p>
  
  <p>Thanks</p>
