Hi,
as fare as I understand the package (havn’t though done much with it, so
I
might be wrong), it is designed for very “practical” purpose (ie
phenomenology.) Many problems can be subsummarized in a larger frame
of
mathematics. Given the type system of AXIOM, it would be, in my eyes,
a
fraud to implement something like “Dirac matrixes” and trace rules,
while
this is a closed structure in a *-autonomous category. However, I am
still
not able myself to give AXIOM code for such a vast general thing.
Most CAS do _not_ document actual algorithms. Its even very difficult
(as
a non expert)= to find/lookup the currently favored algorithms (for
say
comparison with own better(?) ones). So I consider the pamphlet idea to
be
one of the most important of AXIOM and would support a FeynCalc
package
iff its really _fully_ documented via pamphlet format _including_
all
algorithmical details.
