# This script will download and compile various computer programs used
# during the writing of the research paper "Detecting Multiple Authorship
# of United States Supreme Court Legal Decisions Using Function Words",
# by J.S. Rosenthal and A. Yoon (2009), to appear in Annals of Statistics,
# available at:
# 
#	http://probability.ca/jeff/research.html
# 
# The software automatically downloads and sorts plain-text versions
# of United States Supreme Court decisions, using the Justia source
# provided at supreme.justia.com.
# 
# It then performs various statistical analyses on the text of these
# decisions, including the frequency of various "function words" and more.
# 
# The programs are designed for use only on linux/unix/Mac machines.
