# The following files are required:
#
# Main source archive from GitHub
#   This is the source of Cargo, taken from GitHub.
#
# :bootstrap
#   Like Rust, this is a prebuilt "cargo" used to bootstrap it, because
#   Cargo is a standard Rust package itself.
#
# :registry
#   Cargo clones several Git repositories for its dependencies and
#   caches them in its "registry". This is an archive of this registry
#   so nothing is downloaded during the build.
#
# :rust_installer
#   This is a collection of mainly shell scripts which are used to
#   install Cargo.
