+# Build a new PKI which is rooted on an intermediate certificate generated
+# by ./build-inter or ./pkitool --inter from a parent PKI.  The new PKI should
+# have independent vars settings, and must use a different KEY_DIR directory
+# from the parent.  This tool can be used to generate arbitrary depth
+# certificate chains.
+#
+# To build an intermediate CA, follow the same steps for a regular PKI but
+# replace ./build-key or ./pkitool --initca with this script.
+
+# The EXPORT_CA file will contain the CA certificate chain and should be
+# referenced by the OpenVPN "ca" directive in config files.  The ca.crt file
+# will only contain the local intermediate CA -- it's needed by the easy-rsa
+# scripts but not by OpenVPN directly.
