# TODO(james): There is a set of static files that emscripten will always
# attempt to either rebuild or source from a cache. Ideally, we would make
# the build of these files part of the normal build process; however, the
# emscripten compiler handles sandboxing poorly for these files and so it
# is simplest to just manually run emscripten outside of the sandbox and
# copy over the cache folder for now.
