+
+This document contains the most important parts of the GF Resource Grammar API.
+It has been machine-generated from the source files; each chapter gives a link
+to the relevant source files, which give more information. Some of the files have
+not yet been prepared so that the machine generated documentation has the right 
+format.
+
+Since the character encoding is UTF-8 for Russian and Latin-1 for other 
+languages, you
+may have to change the encoding preference of your browser when reading different
+parts of the document.
+
+The second-last chapter gives instructions on how to "browse" the library by 
+loading the grammars into the ``gf`` command editor.
+
+**New**: Browsing by syntax editor 
+[directly on the web ../../../demos/resource-api/editor.html].
+
+The last chapter contains a brief example of how application grammars can
+import resource modules. At the same time, it illustrates a "design pattern" for 
+using the resource API to build functor-based applications
