Re: Powersem to load book or report class

Hi Pascal,

first of all, sorry for the very late reply. I hope you are still
with us...

I'll have a lot of time for working of TeXPower this summer,
so I hope you'll keep up your valuable contributions.

Unfortunately, it seems you're referring to an old version
of TeXPower, so the system has diverged in some parts from
your suggestions.

I'll try to merge both as good as possible, please comment
on my `solutions'.

In the meantime, there's a macro \baseclass which is used as 
the name of the class to load if the KOMA option is set, initially
defined as 

\providecommand{\baseclass}{scrartcl}

which I redefine for instance to scrreprt to have slides with
\chapter.

But maybe the KOMA option is misleading in this case...

I added an Option UseBaseClass which is equivalent.

No. Both were just errors left from different early stages of
development. Both are fixed now.

I've disabled \portraittrue if the article option was given, but
I'm not convinced ;-)

I'm afraid this whole matter needs a much deeper looking into
(and rewriting) than I've done previously...

Right.


Concerning your code:

I've added options reportclass and bookclass which are defined in
terms of the (more flexible) pre-existing \baseclass.

Instead of removing \portraittrue, I replaced it by 
\ifarticle\else\portraittrue\fi
to disable it only when making articles.

Could you try the latest CVS version of powersem I've just uploaded?
