+"""Process Apache (or similarly formated) log files using ``apachelog``.
+
+Use the options to build a parser and list of processors.  Each file
+listed on the command line will be parsed by this parser and processed
+by each processor.  After processing is complete, interesting
+information from each processor will be printed to stdout.
