+# This script expects the server can serve files on the Web. Also expects curl.
+# It uses an HTML template instead of the raw text file because browsers
+# sometimes do not expect UTF-8 by default and this is always what I upload.
+#
+# You need to provide those 3 env variables:
+# - REMOTE_DEST: the SSH destination to reach
+# - REMOTE_WWW: the remote path where the HTML file will be stored
+# - REMOTE_URL: the URL of the directory to print; file name is appended
