#  This module has more code than is actually necessary for the functi
+onality provided.
#  I was originally writing a module for another function, and this ca
+me out of it.  The
#  @articles array that is returned from get_article_list() contains a
+n array reference
#  that has the articles name, prefixed by the string 'node_id=xxx:', 
+where 'xxx' is the
#  number the article title refers to, the reputation of the article, 
+and the date the
#  article was written.  I'm sure you can imagine some uses for this..
