+# This file is designed to automatize the CA tasks such as:
+#  -> init  : create the initial CA tree and the CA root certificate.
+#  -> newcsr: create a new private key and csr. $name and $email must be set. C, ST, L, O, OU may be overwitten (example: make newcsr C=FR)
+#  -> cert  : sign a pending CSR and generate the certificate. $name must be provided.
+#  -> revoke: revoke a certificate. $name must be provided.
+#  -> gencrl: update/create the CRL.
+#
+# The file should be located in the directory STATIC_DIR as defined below.
+# The DIR directory will contain the data of the CA. It might be placed in /var.
+# The DIR should also be configured in openssl.cnf file under [ CA_default ]->dir.
+#
+# Here are the steps to install the CA scripts in default environment:
+## mkdir /etc/openssl-ca.static
+## cp Makefile openssl.cnf /etc/openssl-ca.static
+# ( configure the default parameters of your CA in /etc/openssl-ca/openssl.cnf ) ##
+## mkdir /etc/openssl-ca
