+
+One sticky point when defining variables (both on backends and in Emacs
+in general) is that some variables are typically initialized from other
+variables when the definition of the variables is being loaded.  If you
+change the "base" variable after the variables have been loaded, you
+won't change the "derived" variables.
+
+This typically affects directory and file variables.  For instance,
+@code{nnml-directory} is @file{~/Mail/} by default, and all @code{nnml}
+directory variables are initialized from that variable, so
+@code{nnml-active-file} will be @file{~/Mail/active}.  If you define a
+new virtual @code{nnml} server, it will @emph{not} suffice to set just
+@code{nnml-directory}---you have to explicitly set all the file
+variables to be what you want them to be.  For a complete list of
+variables for each backend, see each backend's section later in this
+manual, but here's an example @code{nnml} definition:
+
+@lisp
+(nnml "public" 
+      (nnml-directory "~/my-mail/")
+      (nnml-active-file "~/my-mail/active")
