"""Ping the PingTheSemantcicWeb service

PTSW tracks changed sem wb files, as a sevice for bots.
Using this to indicate that a file has changed will suggest a bot re-index it.
It also provides interesting statistics and lists of documents with 
different vocabularies.

Usage example:

alias ptsw='python /devel/WWW/2000/10/swap/util/ptsw.py'
ptsw *.rdf

Note the map file must be salted to taste to tell PTSW where the
files in your system are pubished.

- removes the extension assuming the URI uses content negotiation
