Typos for "Touch of Class" draft

How to report a typo

Report it under the appropriate chapter title below. Please include the original section number. The page number is less important as it changes. The best is to copy-paste the relevant text extract and mark the faulty word(s), for example by **...**. It is convenient to show the extract as a display (start lines with spaces) and also, if you wish, to give your name.

For example:

In section 16.1, just after the first figure: 
Money, Pass, Map, Louvre, Orsay
Money, Pass, **Louvre, Map**, Orsay
Money, Map, Pass, Louvre, Orsay

The second one is wrong. -- Luchin Doblies, 1.12.2008.

(Indeed Luchin Doblies reported this error -- thanks! BM.) The entry should appear in the section for the corresponding chapter (it does now). I am sorry that I will not be able to respond to individual comments, but I will consider all reports and correct the text as needed.

As errors get corrected I strike them out.

s.111 - The first thing we need in our class is a feature representing the line to be built. ... "We call it (the feature) fancy_line... but the feature is " build_a_line " i guess

       We call it fancy_line.
