A new and improved solve (equation solver)

I tried to mail this at 2 addresses - they failed, so...

The manual page doesn't explain 'a' and 'v' - I found out by looking that the
code that they are 'author' and 'version', but I thought I'd point this out.

Why won't it solve the following:
==================
cubterm = x^3
sqterm = 0 * x^2
linterm = -21.0*x
conterm = 20.0
poly = cubterm+sqterm+linterm+conterm
===================
The old one solved this, given poly = 0 ( It found a single root, anyway ).
The new one won't - it said it needs more info.

Thank you in advance.
