+# This script is responsible for copying, linking, and aliasing all of our build tools such that they are
+# in known paths that we can add to PATH and LD_LIBRARY_PATH. The binaries go into "${SYS_PREFIX}/bin" and
+# the libraries go into "${SYS_PREFIX}/lib". By default, SYS_PREFIX is `/opt/sledge/`, which means that this
+# script is assumed to be executed as root, as in our Docker build container. However, by by setting
+# SYS_PREFIX to a directory that the user has access to, this can be avoided.
+#
+# For example, in the GitHub Actions workflow, SYS_PREFIX is set to the topmost project directory and the
+# environment is updated as follows.
+#
+# SYS_PREFIX="$(pwd)" ./install.sh
+# PATH="$(pwd)/bin:$PATH"
+# LD_LIBRARY_PATH="$(pwd)/lib:$LD_LIBRARY_PATH"
+#
+# This is currently executed
+# - Indirectly via `make install` in the root Makefile, typically when the sledge-dev build container is built
+# - Directly by the GitHub workflow
+#
+# The script takes either wasmception or wasi as the first argument to install either wasmception or WASI-SDK
+# If no argument is provided, wasmception is assumed
+# If either wasmception or wasi is provided, an additional `-d` or `--dry-run` flag can be provided to view the commands
+# and paths that would be generated. This is helpful for sanity checking when setting SYS_PREFIX and using in a new context
