# Note: Forge really wants to manage dependencies via submodules, but that
# workflow is a little awkward. There's currently no support for a more
# traditional package manager workflow (with a package manifest file and
# installation into a subdirectory that can be gitignored).
# Instead, we just specify the dependencies here. make will then take care of
# installing them if they are not yet present.
# When adding a new dependency, make sure to specify the exact commit hash, and
# the --no-git and --no-commit flags (see lib/forge-std below)
