+@section Resetting Configuration
+
+When you dump and restore an image, or when you tweak your configuration,
+you may want to reset the ASDF configuration.
+For that you may use the following function:
+
+@defun clear-configuration
+   undoes any ASDF configuration,
+   regarding source-registry or output-translations.
+@end defun
+
+If you use SBCL, CMUCL or SCL, you may use this snippet
+so that the ASDF configuration be cleared automatically as you dump an image:
+
+@example
+#+(or cmu sbcl scl)
+(pushnew 'clear-configuration
+         #+(or cmu scl) ext:*before-save-initializations*
+         #+sbcl sb-ext:*save-hooks*)
+@end example
+
+For compatibility with all Lisp implementations, however,
+you might want instead your build script to explicitly call
+@code{(asdf:clear-configuration)} at an appropriate moment before dumping.
