>From your description of the situation, you actually have two different
problems - one is the set of reports that you want for a single website,
giving the wrinkles that cachefiles throw up, and the other problem is
doing this for multiple sites. It sounds like some of the difficulty you
are experiencing might be caused by trying to solve both problems at
once.

Once you have it working for a specific case to your satisfaction,
getting it working for the general case should be more straightforward.

For example, rather than using lot's of different config files, it may
be that you only need to change one or two parameters in a config file,
in which case it may simply be more efficient to have a single, common
config file, and call Analog with the additional parameters as command
line arguments instead.

That shouldn't normally be the case. In fact in some situations, Analog
can actually be faster with compressed logfiles, because the I/O
overhead is lower.
