Collection of utility scripts that I put here for the lack of a better place. They

probably should become tasks/targets in the gradle/ant build scripts at some point.

gvrsdk-update.sh: downloads the Google VR SDK and generates all required packages and jar

files needed to build and run cardboard sketches from Processing

perm-parse.py: generates the array of permissions for a given SDK level, to be pasted in

Permissions.java

wear-update.sh: downloads the wearable aar file from a known maven repository, and

extracts the classes jar and copies it inside core/library

gradlew-update.sh: creates the gradle wrapper with the desired gradle version and packs

it in the mode folder to be available when exporting projects using gradle as the build

system
