Hi Felix,

Nice to hear from you again.

You cannot: only the typesetting process generates auxiliary data.
In the future, I typically would like to allow computations,
say in spreadsheets, to generate auxiliary data too, but that is not done.

No, but this is a top priority. Briefly speaking, the following issues
are on top of the list of the current reorganization of TeXamcs:

  1) Stabilization and documentation of the Scheme interface.
     Includes: Guile as a plugin, fully stable module system,
     contextual overloading, basic API for accessing trees.
  2) Completion of DRD system.
  3) Pluggable stylesheet languages.
  4) Stabilization of the typesetter.

Things should be done more or less in this order too, even though
I am quite motivated for 3/4 at the moment (plenty of new ideas...)

Best wishes, Joris
