Update of /cvsroot/python/python/dist/src/Doc/lib
In directory sc8-pr-cvs1:/tmp/cvs-serv17844/Doc/lib

Modified Files:
	libunittest.tex 
Log Message:
Incorporate Skip's suggestion to use SciPy's validation test near
equality.  Note, there is another flavor that compares to a given
number of significant digits rather than decimal places.  If there
is a demand, that could be added at a later date.
