 it walked the Makefile hierarchy trying to clean subdirectories. This

 \subsection{The Top Level Makefile}
+We have added a stanza to separate the build of documents from the build
+of source files. As much as possible we would like to do the document
+builds in parallel with the source builds. We kick off a make for the
+documents in the background and then kick off a make in the foreground
+for the source code. This is independent of using make in parallel and
+instead uses the shell to fork the processes. We have not had much luck
+getting make to build in parallel reliably.
