+
+ScriptFu is a system and a language.
+This is an overview of the language.
+
+### Ancestry
+
+The language descends from TinyScheme from Scheme from Lisp.
+
+### Standards Conformance
+
+There are many dialects of Scheme.
+There are standards specifying language features.
+ScriptFu more or less conforms to the R5RS standard,
+with the notable exception that it lacks hygenic macros.
+
+### Extra features
+
+The ScriptFu language has extra features not in any
+other dialect of Scheme.
+The main feature of ScriptFu language is that it defines the functions
+of the GIMP PDB.
+That is, you can call GIMP from a script.
+Use the *PDB Browser* of the GIMP app to see the GIMP procedures you can call.
+
+There are a few other extra features:
+
+  * Unicode strings using UTF-8 encoding
+  * the byte type
+
+### Summary
+
+Another way of saying this is:
+
+ScriptFu is an interpreter that embeds the TinyScheme interpreter.
+
+The TinyScheme interprets a subset of Scheme R5RS language.
+
+ScriptFu adds extra language features on top of TinyScheme.
