 synopsis:            Parsing hslogger-produced logs.
 description:         
-
   hslogger-reader provides a function to generate a parser for
   <http://hackage.haskell.org/package/hslogger hslogger>-produced logs
   from a hslogger format string (see "System.Log.Formatter"). The
-  accompanying /profiling/ executable demonstrates parsing and computing
-  with a log file in constant memory.
-
-  Also bundled is the /filter-logs/ executable, a command-line tool to
-  filter a hslogger-syle log file.
-
+  accompanying executable demonstrates parsing and computing with a
+  log file in constant memory.
