blogger -> wordpress redirect code
<?
/**
* *** 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.

stick this in anywhere in the <head> .. only on a "Classic"
blogger template. They also have a newer XML-based template language,
but it can't support this usage because it's too strictly proper xml
and can't do the string concatenation trick we need. -->
