You told Analog to read *.log, and it did. If you only want it to read a 
subset of the logs, based on the dates you provide, then put the logic 
into your wrapper application to specify which logfiles fall between 
those dates.

Analog can't assume that the names of the logfiles include useful date 
information - some web servers rotate daily, some weekly, some rotate 
when the file hits a certain size.

Note that if you have a lot of logfiles, you may improve performance 
somewhat by zipping the logs - the CPU overhead of unzipping the files 
pretty tiny, and you can cut your file I/O by 90-95%.
