BTW, would you be interested in working with me on updating the NUT apcsmart

there is a dual aim:
- update the content
- integrate the new documentation (and so protocol) library, using AsciiDoc.

Since a full revamp to AsciiDoc may be too much for a first step, we can
simply rip the html page itself (ie, without the menu) and integrate it as
an html code snipped...
