+The approaches experimented-with so far (later versions do not _necessarily_
+obsolete earlier ones, they're just different):
 
-### v1
-A single, synchronous script, saving state in text files (Bash and AWK).
-
-### v2
-Parallel processes: collectors, cacher and reporters; passing messages over pipes
-(Bash and AWK).
-
-### v3
-Clean-up, polish and further development of main ideas learned in v2.
