+## WARNING: old (pre-0.9.2) example.dup used to give wrong information about

+## carefully.
+##
+## If the encryptkey variable is set:
+## - data is encrypted with the GnuPG public key specified by the encryptkey
+## variable
+## - if signing is enabled, the password variable is used to unlock the GnuPG
+## private key used for signing; else, you do not need to set the password
+## variable
+## If the encryptkey option is not set:
+## - data signing is not possible
+## - the password variable is used to encrypt the data with symmetric
+## encryption: no GnuPG key pair is needed
