+Enabling interactive character set update
+-----------------------------------------
+
+Now that you have read this document, you should rerun your OCR job
+with the --edit-charset option. You probably want to supply --same as
+well, to avoid having to wait for it to page through and recapture all
+the screenshots. So, this time,
+ ./ypp-commodities --edit-charset --same
+and in future, just always run it with the --edit-charset option.
+
+With --edit-charset, when the OCR finds characters it does not
+understand, it will put up an OCR resolution query window. This will
+display the part of the text it is having trouble with, showing where
+it has got to, and allow you to edit the character set database it
+uses for recognising the text.
+
+*This is subtle* and it is important to understand the way the
+machinery works, and the possible mistakes you can make, before
+answering the program. *Please read this documentation*, which
+explains the meaning of the entries you make.
+
+If you need help please ask me (ijackson@chiark.greenend.org.uk, or
+Aristarchus on Midnight in game if I'm on line, or ask any pirate of
+the crew Special Circumstances if they happen to know where I am
+and/or can get in touch).
