I am Vernon Sipple, the person who is acting as ghostwriter for the Della-Vos book on dynamic Internet pages. My task is to give a degree of uniformity to the text, which is being written by 8 persons with varying degrees of English proficiency. As such, there is a one week Iag between the posting of a chapter and my proof reading. During this interval, you will see things such as authors writing _bear_ for _beer_ and programs with awful bugs.
I am posting this answer under the pseudonym of edu500ac, since I could not remember the password for the email that I created for accessing the Femto-Emacs github account. My knowledge of computer science is very basic. I can write small scripts, and that is it. This means that I will need a lot of help to continue with this work. Since you people seem to agree in providing feedback, I decided to put the draft back into github. The members of the Della-Vos group require that the snippets used as examples be very concise, one Latex page, size A4 or letter of 12pt font size, otherwise the programs will be useless in classroom scenarios. Please, keep this in mind when sending feedback. In summary, that means simply reducing the number of lines in program. The shorter the better. Thank you for your interest in the Della-Vos didactic projects. I will seize the opportunity for thanking Lecalle for spotting the bear typo.
