+  Isabelle/ML is a somewhat augmented version of Standard ML, with
+  various add-ons that are indispensable for Isabelle development, but
+  may cause conflicts with independent projects in plain Standard ML.
+
+  The Isabelle/Isar command 'SML_file' supports official Standard ML
+  within the Isabelle environment, with full support in the Prover IDE
+  (Isabelle/jEdit).
+
+  Here is a very basic example that defines the factorial function and
+  evaluates it for some arguments.

+  The subsequent example illustrates the use of multiple 'SML_file'
+  commands to build larger Standard ML projects.  The toplevel SML
+  environment is enriched cumulatively within the theory context of
+  Isabelle --- independently of the Isabelle/ML environment.
