generating User Guide from SVN tree - how to?

… preferably as single documemt in any editable format (rtf, html, …).

To make the aim nearer, I have tried official way via phing, but have got the error as my system has not hhc. Next steps?  ;)

Why do you want such a format? Is PDF version not enough?

hhc is a program of "HTML Help Workshop" from microsoft.

The problem is, it is impossible, say. to set larger font size before printing a chapter or two. Probably my opinion is shifted, but to my taste pdf is the most “undemocratic” format  :)
