+If CURRENT-NAME is a defcustom (more generally, any variable
+where OBSOLETE-NAME may be set, e.g. in a .emacs file, before the
+alias is defined), then the define-obsolete-variable-alias
+statement should be placed before the defcustom.  This is so that
+any user customizations are applied before the defcustom tries to
+initialize the variable (this is due to the way `defvaralias' works).
+Exceptions to this rule occur for define-obsolete-variable-alias
+statements that are autoloaded, or in files dumped with Emacs.
+
 See the docstrings of `defvaralias' and `make-obsolete-variable' or
 Info node `(elisp)Variable Aliases' for more details."
