+\section{Cliques}
+The algebra code sometimes have circular references. The compiler can
+resolve these references directly if all of the required sources
+are in the same source file.
+
+So the idea to remove the BOOTSTRAP code is to cluster the spad
+sources into "cliqueN.spad" files and feed them all to the compiler
+at once.
