The directory 'modules' contains some general purpose routines used by mathbot in its work. The directory 'mathlists' contains the code mathbot uses to update the lists of mathematicians and mathematics articles. Those codes depend on the 'modules' directory. See the file 'Readme.txt' in 'mathlists' for more information. The directory 'missingscience' contains the scripts that are used to update the mathematics section in the list of missing science topics on Wikipedia. These codes need the package WWW::Mediawiki::Client.pm version 0.23 and its dependencies. I hope to convert those codes to using Perlwikipedia.pm instead at some point. The routine wikipedia_login_prototype.pl in modules/bin needs to be renamed to perlwikipedia_utils.pl and a user name and password needs to be specified in order for the codes in 'missingscience' to work.
