title: Setting compiler.theme option for Halo/Flex 4 in FlashDevelop
body: <p>Here's what works with ant build.xml:</p>
  
  <pre><code>&lt;mxmlc file="${module.main.dir}/main.mxml" keep-generated-actionscript="false" output="${module.output.dir}/main.swf" fork="${flex.fork}"&gt;
      &lt;load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/&gt;
      &lt;source-path path-element="${FLEX_HOME}/frameworks"/&gt;
      &lt;compiler.theme file="${FLEX_HOME}/frameworks/themes/Halo/halo.swc"/&gt;
  &lt;/mxmlc&gt;
  </code></pre>
  
  <p>I tried the following values in Project > Properties > Compiler Options > Additional Compiler Options but none of them worked:</p>
  
  <pre><code>-theme=PATH_TO/halo.swc
  -compiler.theme=PATH_TO/halo.swc
  -theme=file=PATH_TO/halo.swc
  -compiler.theme.file=PATH_TO/halo.swc
  -theme.file=PATH_TO/halo.swc
  </code></pre>
  
  <p>Thanks.</p>
