# This script will pull Scudo standalone files from the llvm project and update
# the standalone directory. This is preferred over git submodule and git subtree
# because those tools do not support mirroring a single directory and LLVM is a
# large project.
#
# This script is expected to be run from the root of the `rust-scudo` project.
#
# Usage: pull-scudo.sh
