You are encouraged to do so ;-)

Yes, that's me.  When I started writing pp2latex I was not an expert in
LaTeX and I fear that is still true.

Perfectly right!  I had the intention to change that and will do in the
next release.

Yes, I agree.

Your suggestions are highly appreciated :-)

This is a good idea. The combination of PerlPoint tags and LaTeX commands
(which can be adopted in the prolog) provide a high level of flexibility.

Thank you very much for your work and the posting via perlpoint@perl.org.
I will try to integrate your fixes into the next release.
