<h3>
Description:
</h3>
This function computes s-1 fundamental units of the given
finite maximal order of a global function field F (the
integral closure of k[T] in F),
where s is the number of places of F at infinity. A list
containing the units is returned. The infinite place
of k(T) must have tame ramification in F. See Scho1
for further definitions and algorithms.

"Defining global variables: F, o, oi, one"
kash> AlffUnitsFund(o);
