+.sh CONFIGURATION FILES
+=======================
+
+Shell jobs may use the following features:
+
+ * logging and control flow functions:
+ halt, fatal, error, warning, info, debug, passthru.
+ All such functions take a list of strings a parameters.
+ Those strings are passed to whatever logging mechanism is enabled,
+ and colored if relevant.
+
+ * Using "exit N" is useless, and has unspecified consequences.
+ Just don't do it.
+
+ * when=TIME works as documented above; at may also be written
+ "when = TIME".
+
+ * The $BACKUPNINJA_DEBUG environment variable is set when
+ backupninja is invoked with the -d option.
