+Generating the Schema Descriptions
+
+The tables.txt and tables.html files are generated automatically from
+the tables.xml. This requires an XML processor called Saxon which can
+be downloaded from http://saxon.sourceforge.net/
+
+When Saxon has been downloaded and installed, edit process-saxon.sh
+and make sure that the -jar argument in each of the two Java calls
+points to the location of your saxon7.jar file.
+
+Then run the process-saxon.sh shell script and the .txt and .html
+files will be created.
+
+
+Editing the Schema Description
+
+If you need to edit the schema description, edit tables.xml (according
+to the rules in schema_description.dtd) and re-run the processing
+stage as above to regenerate the .html and .txt files.
+
+The XML stylesheets for creating the HTML and text (Wiki format) from
+the XML are in xml2html.xsl and xml2wiki.xsl - you shouldn't need to
+edit these unless you are adding a new feature to the processing step.
