-\begin{ttbox}

 Each theory definition must reside in a separate file.  Let the file {\it
   tf}{\tt.thy} contain the definition of a theory called $TF$ with parent
 theories $TB@1$ \dots $TB@n$.  Calling \ttindexbold{use_thy}~{\tt"}{\it
   TF\/}{\tt"} reads file {\it tf}{\tt.thy}, writes an intermediate {\ML}-file
-{\tt.}{\it tf}{\tt.thy.ML}, and reads the latter file.  Any of the parent
-theories that have not been loaded yet are read now by recursive {\tt
-  use_thy} calls until either an already loaded theory or {\tt Pure} is
-reached.  Therefore one can read a complete logic by just one {\tt use_thy}
-call if all theories are linked appropriatly.  Afterwards an {\ML}
+{\tt.}{\it tf}{\tt.thy.ML}, and reads the latter file. \indexbold{automatic
