Re: LaTeX & DFSG
Note to LATEX-L readers: it does indeed seem that Frank and David are
making progress in a reasonable negotiation at debian-legal towards a
reconciliation of LPPL and the Debian Free Software Guidelines.
There is something I do not understand:

Absolutely. The LaTeX world has always had that. There are, however,
both good and bad approaches.
I hope we are straight on the distinction between users and package
or class authors. Everybody in the LaTeX world has freedom, but
the mechanisms for breakage-free exercise of that freedom depend on

I don't follow the allusion to cascading change requirements.
Could someone pose a simple example? Or was the cascade a nightmare?
Gratuitous marginally related postscript: Workers needed.
A great deal of new freedom can be had by using an XML layout document
type that models LaTeX. With that one can have all kinds of
processing pipelines for billions and billions of fussy taste-based
decisions using LaTeX typesetting at the end, with reliability resting
importantly on respect for LPPL. GELLMU can be used for a
free-standing LaTeX-like markup interface to such a document type.
Please understand though that this is not about translating LaTeX
documents into XML; it is for new documents.
