<?
/**
 * *** THIS NEEDS TO BE EDITED FOR A NEW INSTALLATION ***
 *
 * this is supposed to be called as e.g. 
 *   http://anyall.org/blog/blogger/http://socialscienceplusplus.blogspot.com/2008/10/mydebatesorg-and-poten
tially-coolest.html 
 * and then redirect to e.g. 
 *   http://anyall.org/blog/2008/10/mydebatesorg-online-polling-and-potentially-the-coolest-question-corpus-
ever/
 *
 * It accesses wordpress's own metainfo saved from the blogger migration,
 * to guarantee redirection to the correct new version -- no hacks with strings.
 * 
 * So there are 2 redirects total:
 *   (1) the blogspot.com page meta-refreshes to here
 *   (2) this "page" sends to the final wordpress post url
 *
 * This script is "installed" by placing it directly in the wordpress root.
