A new version (1.31) of TeX/Mathematica is available by anonymous ftp from chem.bu.edu (128.197.30.18) in directory /pub/tex-mathematica. TeX/Mathematica is a set of tools that provide facilities of Mathematica Notebooks in a UNIX environment, under GNU Emacs. They permit interaction between a text and a Mathematica buffer and, if desired, the use of TeX/LaTeX to annotate Mathematica-based explorations and programs. Inclusion of Mathematica-generated graphics in TeX/LaTeX documents printed using PostScript is supported. The tools also support the automatic generation of Mathematica packages from TeX/Mathematica documents, using a WEB-like notation. With these tools one can interactively develop and refine teaching and research documents. The interactive nature of the tools encourages Mathematica-based exploration as a natural part of the writing process. The new features of this version pertain to cells that are part of Mathematica packages: (1) individual cells containing package references are now assembled on the fly and sent to Mathematica, and (2) output can now be captured into such cells, but with such output ignored in package assembly. With these changes, cells that contain cell references behave as ordinary Mathematica cells as far as communication with Mathematica is concerned. A related new feature is that the delimiter between the input and output portions of Mathematica cells has been changed to a non-blank line, so that the input portion of package cells can continue to contain blank lines, to control spacing between package components. The output marker can be easily changed, using the new function tex-mma-convert-output-marker. Comments, etc. always welcome. Thanks Dan Dill dan@chem.bu.edu
