I started working on a new way of summarizing texts. This time the goal it to take a \
group of articles and join them to a single article; I do so by taking one article \
from the group and replacing parts of it with parts of the other articles that have \
the same signature. 

The code is still hackish , leaks buckets and is NOT ready for any use. but it's in \
the cvs under examples/;

Here (Attached) is a quick demo of an article I joint from various sources;
                                                                                      \

The storm brought several inches of snow to Virginia and Maryland on Friday, and road \
crews were preparing for a second onslaught with flurries overnight expected to turn \
to heavy snow.   FORECASTERS SAID the system could hit even harder over the weekend, \
with total snow accumulations of up to two feet in Massachusetts and near-blizzard \
conditions in parts of Maine and New Hampshire.  These included a blizzard warning \
for Saturday for the New York City area.  Many schoolchildren got an early start to \
their weekend when dozens of schools closed early on Friday.  More than 80 \
fender-benders were reported on the New Jersey Turnpike, where the speed limit was \
reduced from 65 mph to 35 mph because of dangerous conditions.  Winds from 20 to 40 \
mph with higher gusts are forecast Saturday near the coast from New York City north \
to Boston.  "We're hoping the forecasters are wrong, but if they're not, we're \
trusting that people will be staying home with their families and off the road so we \
can get our job done," said Anna Farneski, spokeswoman for the Bergen County, N.J.  \
The warning means forecasters expect sustained wind speeds or frequent gusts of 35 \
mph or faster with considerable falling or blowing and drifting snow that will drop \
visibility to zero at times.  "I love storms, but I don't like shoveling," Stevenson \
said.  Forecasters in Massachusetts predicted up to 18 inches of snow through Sunday. \
By Friday evening, The National Weather Service had winter storm warnings in effect \
from Virginia and West Virginia northeast into southern New England.  About 100 \
flights were canceled at Philadelphia International Airport on Friday, and some \
flights were delayed at Washington Dulles International Airport.  Flights were \
canceled at New York's La Guardia, New Jersey's Newark Liberty International Airport, \
Boston and Philadelphia airports, and others were delayed by several hours. Kennedy \
airports and New Jersey's Newark Liberty International, according to the Port \
Authority of New York and New Jersey.  The storm had already brought a mixture of \
ice, freezing rain, sleet and snow in mountain regions of North Carolina, Virginia \
and West Virginia on Thursday.  The Weather Service said the complex storm system \
brought in snow and sleet on Friday, which changed to rain in some places as \
temperatures warmed through the day.  About 100 flights were canceled at Philadelphia \
International Airport on Friday, and some flights were delayed at Washington Dulles \
International Airport. Cancellations and delays also were expected Saturday at New \
York's La Guardia and John F.  "We're loving it," said Tana Graham, visiting New York \
City from Jackson, Miss.        "The salt is here, the trucks are ready, the chains \
are on, and New York is prepared for the assault," Mayor Michael Bloomberg said \
Friday. "I just bought 100 pounds of ice melt and we took out our snow shovels last \
night.  "The salt is here, the trucks are ready, the chains are on, and New York is \
prepared for the assault," New York City Mayor Michael Bloomberg said Friday. At \
least one death was blamed on the storm, that of a 23-year-old man who was killed in \
an accident on a slick road in Virginia.   By Jacqueline Larma, AP  Friday's snow was \
like a warm-up for the main event with even heavier snow and high winds making travel \
even harder on Saturday, forecasters said. Four to 8 inches were expected in the \
Baltimore region.
