Anyone know the new way to set a manifest source location in the experimental plugin?

```
dependencies {
    classpath "com.android.tools.build:gradle-experimental:0.1.0"
}

```

I believe I have java and resources correct, but can't figure out manifest:

```
android.sources {
    main {
        //manifest.source.srcDir 'library'
        manifest.srcFile = file('library/AndroidManifest.xml')
        //manifest.srcFile 'library'
        resources.source.srcDir 'library/res'
        java.source.srcDir 'library/src'
    }
}

```
