+"""Fetch Java versions with their dates from https://www.java.com/releases/.
+
+This script is using requests-html (https://requests-html.kennethreitz.org/)
+because https://www.java.com/releases/ needs JavaScript to render correctly.
+
+requests-html is using pyppeteer internally for executing javascript. And
+pyppeteer is relying on Chromium, which is automatically downloaded  in
+~/.local/share/pyppeteer by the library. This path can be overridden by
+declaring a PYPPETEER_HOME environment variable. Unfortunately exporting this
+variable in the python script does not work, so it has to be done before this
+script execution.
