Please edit the vars script to reflect your configuration,
\nthen source it with \"source .\/vars\".
\nNext, to start with a fresh PKI configuration and to delete any
\nprevious certificates and keys, run \".\/clean-all\".
\nFinally, you can run this tool (pkitool) to build certificates\/keys.<\/p>\n
