Create artifact bundle for Maven Central upload
# I found the instructions for setting up Maven Central upload in pom.xml too involved.
# This does the job as well, though it requires manually uploading it in Maven Central's
# web interface as an artifact bundle.
# Usage:
# 1. Make sure your project is ready and the release version checked out
# 2. Change GPGKEY to point to your key in this script
# 3. Run this script in the directory containing pom.xml
