for blogging,i hacked txt2tags.py v2.4, so share at first, i will try
to merge into v2.5:
   + for make TOC can click,and make TOC anchor unique:
       - e.g http://blog.zoomquiet.org/pyblosxom/utility/Subversion/
       - in this page include several t2t export xhtml body
       - include several TOC guider list
       - with my hacked,every TOC list can click jump to that chapter
       - and every chapter can click back the right entry top
       hacking: appended one global ver as
       XHTML_TOPTOP = ""
