Here is the first paragraphs. I'll type some more just so we have more
than one line. At least I hope it will be enough. Here's some verbatim
text:

\begin{code}{}
foobar.
dhe#%^@&#(*#&^*(@)#.
barfoo.
\end{code}

\noindent
Centered:

\begin{code}{c}
foobar.
dhe#%^@&#(*#&^*(@)#.
barfoo.
\end{code}

\noindent
Left-adjusted:

\begin{code}{l}

\end{code}

\noindent
Right-adjusted:
