-# In order to provide support for multiple Arduino Lint releases, Documentation is versioned so that visitors can select
-# which version of the documentation website should be displayed. Unfortunately this feature isn't provided by GitHub
-# pages or MkDocs, so we had to implement it on top of the generation process.
-#
-# Before delving into the details of the generation process, here follow some requirements that were established to
-# provide versioned documentation:
-#
-# - A special version of the documentation called `dev` is provided to reflect the status of Arduino Lint on the
-#   `main` branch - this includes unreleased features and bugfixes.
-# - Docs are versioned after the minor version of an Arduino Lint release. For example, Arduino Lint `0.99.1` and
-#   `0.99.2` will be both covered by documentation version `0.99`.
-# - The landing page of the documentation website will automatically redirect visitors to the documentation of the most
-#   recently released version of Arduino Lint.
-#
-# To implement the requirements above, the execution of MkDocs is wrapped using a CLI tool called Mike
-# (https://github.com/jimporter/mike) that does a few things for us:
-#
-# - It runs MkDocs targeting subfolders named after the Arduino Lint version, e.g. documentation for version `0.10.1`
-#   can be found under the folder `0.10`.
-# - It injects an HTML control into the documentation website that lets visitors choose which version of the docs to
-#   browse from a dropdown list.
-# - It provides a redirect to a version we decide when visitors hit the landing page of the documentation website.
-# - It pushes generated contents to the `gh-pages` branch.
-#
-# In order to avoid unwanted changes to the public website hosting the Arduino Lint documentation, only Mike is allowed
-# to push changes to the `gh-pages` branch, and this only happens from within the CI, in the "Publish documentation"
-# workflow: https://github.com/arduino/arduino-lint/blob/main/.github/workflows/publish-docs.yml
-#
-# The CI is responsible for guessing which version of Arduino Lint we're building docs for, so that generated content
-# will be stored in the appropriate section of the documentation website. Because this guessing might be fairly complex,
-# the logic is implemented in this Python script. The script will determine the version of Arduino Lint that was
-# modified in the current commit (either `dev` or an official, numbered release) and whether the redirect to the latest
-# version that happens on the landing page should be updated or not.

+# In order to provide support for multiple project releases, Documentation is versioned so that visitors can select
+# which version of the documentation website should be displayed. Unfortunately this feature isn't provided by GitHub
+# pages or MkDocs, so we had to implement it on top of the generation process.
+#
+# - A special version of the documentation called `dev` is provided to reflect the status of the project on the
+#   default branch - this includes unreleased features and bugfixes.
+# - Docs are versioned after the minor version of a release. For example, release version `0.99.1` and
+#   `0.99.2` will be both covered by documentation version `0.99`.
+#
+# The CI is responsible for guessing which version of the project we're building docs for, so that generated content
+# will be stored in the appropriate section of the documentation website. Because this guessing might be fairly complex,
+# the logic is implemented in this Python script. The script will determine the version of the project that was
+# modified in the current commit (either `dev` or an official, numbered release) and whether the redirect to the latest
+# version that happens on the landing page should be updated or not.
