Thanks to the many who replied to my questions about setting
figures full of typing rules. Your suggestions were as follows:
* \fbox left justified on a line by itself just before \mathpar
(possibly with {} \and ... to make room)
Example detail:
\newcommand{\judgshape}[2][]{\begin{flushleft}\fbox{\(#2\)~#1}\end{flushleft}}
...
\judgshap[(where \(A\) is well formed)]{\Gamma \vdash e : A}
\begin{mathpar}
...
\end{mathpar}
* \fbox on its own line in {mathpar} and thus centered
* \fbox in mathpar with very ugly hack to force left or right alignment
* \fbox in mathpar with nice hack to force left alignment:
\fbox{$e \cbvstep e'$}\hfill\\
* Check out back end of `ottalt` package (used with Ott) or ottlayout.sty
Thanks again!
