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 included "factbook.txt" was obtained from the CIA files (which
were downloaded in January 2002), by the following procedure :

1. Concatenate all html files into one big file
2. Load into netscape and convert to ascii text
3. Replace "^Q^J " by "^Q^J" (i.e., strip off initial blank character)
4. Replace sq km by km
5. Remove all tags [Map of ...], [CIA Seal...] etc.

This produces a text file which is still not correctly formatted. The
goal of `fact_extract` is to reformat this stuff into something that
is easily understood by xrmap or TeX (or html browsers).

To produce data in ASCII text form (respectively in TeX or HTML formats), type

make ascii
make tex
make html
