Thanks for the reminder about KnowNews, I linked to it from the
kn_apps/index.html page and checked the new index.html in.  I'll
have to make a new tarball soon, I keep committing small but
useful changes.  Make sure if you have a CVS checkout to regularly
do CVS updates so you stay... er... up to date.

For example, do_method=whoami was added to pubsub.py ... of course, when
running pubsub.py I see that clens does not, at present, work.  Will need
to go through it carefully to determine why.

Good point.

The new check-in of cxx_pubsub, among other things, contains

   mod_pubsub/cxx_pubsub/LibKN/Apps/RSSPub

which could be used to create such a service.  It uses the new LibKN
(sorry Fred, there are multiple libkn's now!) available in cxx_pubsub,
based on a C++ framework that has the following features:

  * Supports all Windows platforms: Win98, WinME, WinNT, Win2K, WinXP,
and WinCE 3.0.
  * Multiple interfaces to the C++ code: COM/ActiveX and .NET.
  * Thread-safe supporting multithreaded applications.
  * Doxygen comments.
  * cppunit-based unit tests.
  * Sample applications.
  * Based on WinInet to support proxies and SSL easily.

Check it out, you won't be disappointed.

Another good point.  Mike's on a roll.  :)

Websites Complaining About Screen-Scraping
