+# This file provides the function `commit_toolstate_change` for pushing a change
+# to the `rust-toolstate` repository.
+#
+# The function relies on a GitHub bot user, which should have a Personal access
+# token defined in the environment variable $TOOLSTATE_REPO_ACCESS_TOKEN. If for
+# some reason you need to change the token, please update `.travis.yml` and
+# `appveyor.yml`:
+#
+#   1. Generate a new Personal access token:
+#
+#       * Login to the bot account, and go to Settings -> Developer settings ->
+#           Personal access tokens
+#       * Click "Generate new token"
+#       * Enable the "public_repo" permission, then click "Generate token"
+#       * Copy the generated token (should be a 40-digit hexadecimal number).
+#           Save it somewhere secure, as the token would be gone once you leave
+#           the page.
+#
+#   2. Encrypt the token for Travis CI
+#
+#       * Install the `travis` tool locally (`gem install travis`).
+#       * Encrypt the token:
+#           ```
+#           travis -r rust-lang/rust encrypt \
+#                   TOOLSTATE_REPO_ACCESS_TOKEN=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+#           ```
+#       * Copy output to replace the existing one in `.travis.yml`.
+#       * Details of this step can be found in
+#           <https://docs.travis-ci.com/user/encryption-keys/>
+#
+#   3. Encrypt the token for AppVeyor
+#
+#       * Login to AppVeyor using your main account, and login as the rust-lang
+#           organization.
+#       * Open the ["Encrypt data" tool](https://ci.appveyor.com/tools/encrypt)
+#       * Paste the 40-digit token into the "Value to encrypt" box, then click
+#           "Encrypt"
+#       * Copy the output to replace the existing one in `appveyor.yml`.
+#       * Details of this step can be found in
+#           <https://www.appveyor.com/docs/how-to/git-push/>
+#
+#   4. Replace the email address below if the bot account identity is changed
+#
+#       * See <https://help.github.com/articles/about-commit-email-addresses/>
+#           if a private email by GitHub is wanted.
