The pamphlet is intended to reference other pamphlets thru the
bibliogrphy. Pamphlets are intended to stay very close to the
what scientists know and extending it carefully. The next step
is to introduce semantic latex tags like \concept{ }

Yes. Magnus represents a competely new challenge because it contains
almost no algorithms. Almost everything is a procedure and may not 
terminate. You kick off several algorithms in parallel and let them
compete for a solution. Infinite Group Theory is provably non-algorithmic
for almost every question.

erm,... I retype the papers from pdf format to TeX format and then
include the code (making it a pamphlet). Almost no-one posts TeX
so there appears to be no choice. Fateman has been looking at
recognizers for file formats but a push to collect and store the TeX
files would save a tremendous amount of time. In the last year I've
retyped approx 500 pages of pdf to TeX.
