+## Install Script ##
+
+# This is the most important part of the Appveyor configuration. This installs the version of Rust
+# specified by the 'channel' and 'target' environment variables from the build matrix. This uses
+# rustup to install Rust.
+#
+# For simple configurations, instead of using the build matrix, you can simply set the
+# default-toolchain and default-host manually here.
