Hello,
I should probably put that stuff into trunk, but before it gets
accidentially removed from my hard disk I want to archive it via the
mailing list.
With it one can easily print the series and structures without invoking
Axiom.
Compile with
trunk/combinat/src>aldor -fx -Y . -i ../include/ -l combinatd -lalgebrad
-laldord -DDEBUG speciestest.as
