/**
* Provides an entry point for the resource processing stages.
*
* <p>A single entry point simplifies the build tool binary configuration and keeps the size of tool
* jar small, as opposed to multiple tools for each process step. It also makes it easy to prototype
* changes in the resource processing system.
*
* <pre>
* Example Usage:
* java/com/google/devtools/build/android/ResourceProcessorBusyBox\
* --tool PACKAGE\
* --sdkRoot path/to/sdk\
* --aapt path/to/sdk/aapt\
* --adb path/to/sdk/adb\
* --zipAlign path/to/sdk/zipAlign\
* --androidJar path/to/sdk/androidJar\
* --manifestOutput path/to/manifest\
* --primaryData path/to/resources:path/to/assets:path/to/manifest\
* --data p/t/res1:p/t/assets1:p/t/1/AndroidManifest.xml:p/t/1/R.txt:symbols,\
* p/t/res2:p/t/assets2:p/t/2/AndroidManifest.xml:p/t/2/R.txt:symbols\
