# Package binary build of Trusty, QEMU, AOSP, and scripts for standalone use

# Inputs:
# QEMU_PACKAGE_ARCHIVE: output package archive to create (.zip or .tar.gz)
# QEMU_PACKAGE_FILES: files and folders to include in the package archive
# 		These files/folders must be valid make targets, as they will be included
# 		as pre-requisites to the package zip.
# QEMU_PACKAGE_EXTRA_FILES: additional files and folders to include in the
# 		package archive, which are not make targets. These files must be created
# 		by a target in QEMU_PACKAGE_FILES.
