HTML files are used to display what you want to see from the information coming from SPD on any device with a browser. SPD sends a lot of information via its webserver, and users can write their own html to display what they like.
A number of html files are included in the complete download of SPD.
When users develop html themselves and want to make it available to other users (via an e-mail to sailingpd (;-) capolavoro.nl ) it will be placed here, without the need to create and get a new complete download of SPD.
Just pick up some new html here!
