   of source files that may contribute to an output document.  Each
   session is derived from a single parent, usually an object-logic
   image like \texttt{HOL}.  This results in an overall tree structure,
   which is reflected by the output location in the file system

   \medskip The easiest way to manage Isabelle sessions is via
   \texttt{isabelle mkdir} (generates an initial session source setup)
   and \texttt{isabelle make} (run sessions controlled by
   \texttt{IsaMakefile}).  For example, a new session
