+# Borrowed from https://github.com/BurntSushi/ripgrep
+#
+# The way this works is the following:
+#
+# The create-release job runs purely to initialize the GitHub release itself
+# and to output upload_url for the following job.
+#
+# The build-release job runs only once create-release is finished. It gets the
+# release upload URL from create-release job outputs, then builds the release
+# executables for each supported platform and attaches them as release assets
+# to the previously created release.
+#
+# The key here is that we create the release only once.
+#
