the cvs snapshot I uploaded some time ago on the download page is not  
with examples and pseudos, I don't remember why. As soon as the  
download page
is updated to something more functional, I'll upload a new complete  
cvs snapshot,
together with the stable version that has unfortunately disappeared  
into the
"previous versions" section. Sorry for the mess.

there is no "guide" and there will never be one, I guess. The tests  
is an attempt to write better automated tests than those presently  
in the 'tests and examples' directory examples/. Tests should be
- fast to execute (i.e. tens of minutes at most, not hours)
- exhaustive (i.e. test all features)
- modular (i.e. test a single code at the time)
- boolean (i.e. the result should be ok or not ok)
Examples should be
- realistic (i.e. reflect real-life cases)
- simple to read and to understand
What is contained in examples/ iobeys to none of the above criteria.  
This is why
I started to write tests/ . I am quite satisfied with the result, but  
unfortunately only
pw.x is covered. Attached: the results of tonight's tests
