 In contrast to the highly interactive mode of Isabelle/Isar theory
   development, the document preparation stage essentially works in
   batch-mode.  An Isabelle \bfindex{session} consists of a collection

   tree structure, which is reflected by the output location in the
   file system (usually rooted at \verb,~/isabelle/browser_info,).
