+# Simple script testing that the different ledger-cli.org subdomain redirects work as expected.
+
+# Tests consists of 2 lines (blank lines are ignored)
+# The first line starting with a octorhorpe (#) is a brief description of the test that will be echoed.
+# The second list must be quoted with single quotes and consists of:
+#    1. an URL to query
+#    2. a single space ( )
+#    3. the expected HTTP status code
+#    4. a single colon (:)
+#    5. the expected redirect URL
+#
+# For example the following test:
+# 'git.ledger-cli.org/ledger/releases/latest 302:https://github.com/ledger/ledger/releases/latest'
+# can be read as
+# When requesting the URL `https://git.ledger-cli.org/ledger/releases/latest`
+# it is expected that the server responds with a `302` and a location header value of
+# `https://github.com/ledger/ledger/releases/latest`
