Oh, interesting this pairedbox thing (it's undocumented,
though). I was hoping to be able to do it like this:
\defineframedtext[lepi][align=raggedright,width=fit,offset=0pt,frame=off,location=left]
\defineframedtext[repi][align=raggedright,width=fit,offset=0pt,frame=off,location=right]
\definepairedbox[epi][location={right,top}]
\placepairedbox[epi]
{\startlepi
{\bf Coordinatore}\par
prof. F.~Nicolosi
\stoplepi}
{\startrepi
{\bf Tutor}\par
prof. G.~Russo
\stoprepi}
But it won't work because the second box (repi) gets placed
with its LEFT margin on the right margin of the page,
whereas I needed to be with its right margin at the right
margin of the page. I think the problem is that, from what I
get by reading the source, in paired boxes are not treated
equally.
no, you need to bypass the location handling in framed texts
so, replacing left and right by none should do the trick, however, i
found out that this demands an extra line of code in core-rul.tex (see
'newer' below)
\def\dodostopframedtext#1#2% % no \baselinecorrection, see faq docs
{\endgraf
\removelastskip
\doifvalue{\??kd#1\c!depthcorrection}\v!on % local and global
{\forgetall
\vskip-\struttotal
\verticalstrut
\egroup
\forgetall
\vskip-\lineheight
% will be an option, not default
% \setbaselinecorrections
% \donegbotbaselinecorrection
\verticalstrut}
\stopboxedcontent
\stopcolor
\egroup
\doif{#2}\v!none\insidefloattrue % new
\doif{\framedtextparameter{#1}\c!location}\v!none\insidefloattrue %
newer
\ifinsidefloat
\box\framebox
\else
\doplacement[\??kd#1][\c!depthcorrection=\v!off]{\box\framebox}%
\fi
\egroup}
Basically, the rpbolem seems to be that the width of the
lepi framed text is not the 'natural width' of the text,
despite the width=fit command ... why is this so?
see \doplacement in the previous code, you need to have the then branch;
placement is for placemen tin the running text (and looks at the text
width)
