\section{Introduction}
Welcome to SchemeWEB.

\section{Comment sections}
Here, we are in comment section, so, the text can be formated with
LaTeX.

For example, we can say that ${(a + b)}^2 = a^2 + 2ab + b^2$, and use
any other commands.

\section{Code section}

If a line begins with a '(', then, a code section begins, like in

(define (foo bar) 
  #f)

The comments inside code section are also considered as LaTeX source,
so, you can write things like

(define (f alpha) ; Returns $2 * \alpha$
  (* alpha 2))

\section{File inclusion}

Off course, you can include other documents as usual with
\verb!\input! :

\input{SampleOfInclusion}

Enjoy yourself with SchemeWEB !
