+There is often a need to generate test certificates automatically using
+a script. This is often a cause for confusion which can result in incorrect
+CA certificates, obsolete V1 certificates or duplicate serial numbers.
+The range of command line options can be daunting for a beginner.
+
+The mkcerts.sh script is an example of how to generate certificates
+automatically using scripts. Example creates a root CA, an intermediate CA
+signed by the root and several certificates signed by the intermediate CA.
+
+The script then creates an empty index.txt file and adds entries for the
+certificates and generates a CRL. Then one certificate is revoked and a 
+second CRL generated.
+
+The script ocsprun.sh runs the test responder on port 8888 covering the
+client certificates.
+
+The script ocspquery.sh queries the status of the certificates using the
+test responder.
