but does not document @afourlatex, @afourwide and @pageparams.
@pageparams was a typo, that cmd doesn't exist.
What are the differences among @afourpaper, @afourwide and
@afourlatex ?
I have never seen the output from them, I just inherited the commands.
Is there any other undocumented paper size command like
@afivepaper (or the like)?
No, but if you look at texinfo.tex you'll see how to define your own.
Just copy @afourpaper and change some of the numbers. If you tell me
the correct values for A5 paper (or other standard paper sizes), I'll
add it.
Is there other ways to do it? Is it
possible to set the margin sizes easily?
Yes, by adding the new command to texinfo.tex.
It would be nice to have it at the command level ...
Yes, I know :).
Thanks,
