+// Sample module for importing conversation data from Reflection CMS. Some preparation was used to 
+// dump relevant posts, categories and comments into individual JSON files, and also JSON dump of 
+// the user table to search for avatars. Importation was also batched in sets of 20 posts per page
+// visit so as to survive shared hosting process limits. This provides some clues as how to handle 
+// WordPress imports, which use a somewhat similar DB structure. The batching and individual files
+// might not be needed in VPS environments. As such this could be considered an extreme test case, but
+// the importation was successful in all regards using this code. The module URL was visited repeatedly
+// with a browser until all the posts had been imported.
