# How to build for PNaCl on Linux.
#
# Download the Native Client SDK.
# Run naclsdk update pepper_XX. The pepper version must be pepper_37.
# Set NACL_SDK_ROOT in your environment to nacl_sdk/pepper_XX.
#
# Check out the naclports repository. This was built with
# naclports@b0aaa9899316e157883ee4b54f70affbebd2c3e1.
# Set NACL_ARCH to 'pnacl' in your environment and run 'make sdl'
# from the naclports root.
#
# Come back to the root of vba-m and run
# cmake -DCMAKE_TOOLCHAIN_FILE=CMakeScripts/PNaCl.Toolchain.cmake CMakeLists.txt
# make
#
# This will build a non-finalized PNaCl port to ./vbam and a finalized version
# to src/pnacl/app/vbam.pexe.
#
# The src/pnacl/app folder can be loaded as an unpacked extension into Chrome
# which will run vba-m as a packaged app.
