User documentation for the database server and the gui client. If your user documentation is online then you may omit this file. However, if the documentation is not online, you must provide either a single plain ASCII (not word processor format) text document, which must be called userguide.txt, or multiple HTML files which must all be accessible from a starting point document that must be called userguide.html.
I have only one html file called userguide.html which is structured using internal links, similar with the provided instructions.html. I have a subdirectory where I keep all the images referenced from the html file.
It is a problem if I have only one html file or should I break into more html files? The specification is saying "multiple HTML files" . What do you think ?
