+# - logic-pattern: this is expanded to *logic-pattern* and matched
+#                  against all logics as returned by `isabelle findlogics`
+#                  the first match wins
+# - file: file to open
+# - options: options passed verbatim to 'isabelle emacs'
+#
+# If no logic-pattern is given, the file .isabelle-logic is
+# evaluated: This file should contain one line, being either the logic to load,
+# or '..', which makes the script take the .isabelle-logic in the parent directory.
