There are also CoCoALib fns for computing the chebyshev polynom... -

- Checked-in an update to all Makefiles. Hope it works -- I did mess some things up :-(

18:32 Feature #1007: (makefile) New "clean" target which does not clean documentation

-
- I failed to install LaTeX on the netbook :-(
-
- Can we make it simpler? Reduce the dependencies on external software?
What do we need java for?

- I am trying to build and install CoCoA-5 from source on a "bare-bones" Linux box.
It is proving to be quite tedious ...

- I have a package myself called @taylor@.
Maybe I could show it to you and decide.

- Remember the syntax @NewPolyRing(QQ, "x,y,z");@. That's very expressive!

- Neat idea, but I think we would still have the ambiguity between:
@K["x"]@ and @F["factors"]@ for records (very usef... -

I note that ... -
