'''Preface'''
write up your question on the PEAK mailing list, and we'll try to
get these examples updated with more Windows-specific command lines.)
(Note to all readers: the examples in this document have been
tested against PEAK CVS. Most examples should work with
0.5 alpha 2, but not all will. There could also be synchronization
errors between the examples and the test code, so if you find
something that doesn't work as advertised when run against current
CVS, please let me know.)

}}} Hmm. There's a lot of information and capabilities there. We're
interested in the general format of a logging call, and which logging
calls are provided. Looking through the list of methods, things
like `critical`, '`debug`, `warning`, `error`, and `info` all look
like `critical`, 'debug`, `warning`, `error`, and `info` all look
handy. The other methods we can ignore for now.

enough already!): {{{

Here we are using PEAK's `LogStream` logger. To work, it needs
to know which stream to write to, so we tell it using
`stream=importString('sys.stderr')`. We need to use importString
`stream=importString('sys.stderr')`. We need to use `importString`
because `sys.stderr` is an import path. We also tell the logger
the minimum level of message to log. (Message levels are named the
same as the corresponding method names, but using all caps).
