This may have more to do with boostbook/quickbook than with xpressive, but in my Windows XP FireFox browser, it appears that every place inline code is followed by regular text, there is no space separating them. Spaces also seem to be missing in a few other places, e.g. "usingnamespace" can be seen on http://boost-consulting.com/projects/xpressive/xpressive/user_s_guide.html#x..., as can "representationof" ("representation" is in italics). So this probably applies to all style changes. Also, the full justification of text is difficult to read. I don't think web browsers are smart enough about formatting to make that legible, at least not at the normal smallish text sizes. Also, I think the abbrev "parens" should be changed to the word "parentheses" :) -- Dave Abrahams Boost Consulting www.boost-consulting.com
