* Building the framework

Using ant build file. From root,
$ ant compile
 (SCALA_HOME must be set to Scala home directory, i.e. /opt/local/share/scala

OLD WAY:
    $ scalac -d classes src/main/scala/ProcessingParallel.scala src/main/scala/Worker.scala 

* Building the PageRank example

$ scalac -cp classes -d classes src/main/scala/PageRankParallel.scala src/main/scala/GraphReader.scala

* Running the PageRank example

Command-line arguments: #iterations datadir #pages
$ scala -cp classes processing.parallel.PageRank 10 data/ 2000

Expected output:

Reading wikipedia graph from file...
#vertices: 14672
