Yes, OK, thanks for the reminder, I have now set up logging in
my pyBlosxom.

It seems to me that the apache 2.2 error_log file is *much* noisier
than the apache 1.3 one ever was.  An error in pyBlosxom under apache
1.3 gave a nice straightforward trace-back, under 2.2 it produces far
too much output with too much on each line.  For example a simple
syntax error in my plugin produces the following:-

but the apache 1.3 error log is like this:-
    Traceback (most recent call last):
      File "/usr/lib/python2.5/wsgiref/handlers.py", line 92, in run
        self.result = application(self.environ, self.start_response)
      File "/usr/lib/python2.5/site-packages/Pyblosxom/pyblosxom.py", line 485, in >
        p.run()
      File "/usr/lib/python2.5/site-packages/Pyblosxom/pyblosxom.py", line 185, in >
        self.initialize()
      File "/usr/lib/python2.5/site-packages/Pyblosxom/pyblosxom.py", line 127, in >
        config.get("load_plugins", None))
      File "/usr/lib/python2.5/site-packages/Pyblosxom/plugin_utils.py", line 102, >
        _module = __import__(mem)
      File "/home/chris/webdev/pb/plugins/mywiki.py", line 290
         def makeIndex(thisDir)

None of the "referer:" stuff and none of the date/time and client stuff,
much, much easier to use.
