Hannes,

Somehow I think you are going in a wrong direction in making packages, or
else I don't understand your question. You shouldn't ordinarily have to even
look at the package.m file.

Write a package as an ordinary Mathematica notebook, package.nb. Make all of
the cells Initialization cells. Put each statement in a separate cell. Then
when you first save the notebook, you will be asked if you want to create an
AutoSave Package. Say yes. (If you already have such a notebook you can
change it to an AutoSave package using the Option Inspector.) Then everytime
you edit and save the package.nb notebook the package.m file will also be
updated.

The package.nb notebook is just like a regular notebook and has all the
regular typeset structures such as x^2 where the 2 is actually a
superscript.

As I said, you should never have to look at, or edit, the package.m file.
You do all the editing in the package.nb notebook.

Dear Mathematica experts,

the following problem: Mathematica's typesetting capabilities are nice
in notebooks to improve the readability of equations (powers in
supscript-notation etc.). However, when one saves such a notebook as a
Mathematica-package, all the typesetting information is saved also. In
the package, which is essentially just an ASCII-file, the typesetting
information is useless and sometimes creates errors. At best, it makes
it very hard to read the package using a text editor. Here is an
example, how x^3 entered in supscript notation into the initialization
cell of a Mathematica notebook looks in the package:

\!\(x\^3\)

Upon creating larger packages, Mathematica apparently sometimes does
not balance the parentheses correctly: Reading such a package back to a
notebook, Mathematica complains on syntax errors. I had no choice than
to rewrite all nicely typesetted formulas in the original notebook in
plain Mathematica syntax without any typesetting and to save the
package again.

Now my question: Is it possible to use typesetting in the Mathematica
notebook on one hand, and to save it to a package without any
typesetting information on the other hand?

Thanks for any advice.

Hannes Kessler
