+# The purpose of this script is to create certificates to be able to test ODF signing code.
+#
+# What it does:
+#
+# 1) Create a test root CA.
+#
+# 2) Create an intermediate CA, as signing certificates with a root CA is
+# considered unsafe.
+#
+# 3) Create two client certificates that can be used to sign ODF documents in
+# LibreOffice.
+#
