Comment 1 for bug 3080

Your're right. IMHO, the examples should be changed from the LyX to use the correct classes which comes in
/usr/share/texmf/tex/latex/.

This seems more a problem of the examples directory being packaged rather than the classes. As far as I know from being a latex user,
such classes (old .sty files) never came with specific classes/styles from .org like IEEE por ACM. We always had to dowwnload them
and set environment variables such as TEXINPUTS.

If one changes the example (aa_example.lyx) from
\textclass aa
to
\textclass article

the example works fine, showing that the template where not based on standard LaTeX classes.
