The following data were obtained from the CIA factbook, a huge resource 
of public domain data providing interesting information about all world 
countries. These data are available as html files from

http://www.cia.gov/cia/publications/factbook/

The "factbook_2002.tgz" package was obtained from the CIA html files from
subdirectory geos/ (which were downloaded in January 2003), by compiling
the small 'reformat' utility (just type 'make'), and then running the
'htmlconv' script in the geos/ directory.
