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.
