+
+// Package log4go provides level-based and highly configurable logging.
+//
+// Enhanced Logging
+//
+// This is inspired by the logging functionality in Java.  Essentially, you create a Logger
+// object and create output filters for it.  You can send whatever you want to the Logger,
+// and it will filter that based on your settings and send it to the outputs.  This way, you
+// can put as much debug code in your program as you want, and when you're done you can filter
+// out the mundane messages so only the important ones show up.
+//
+// Utility functions are provided to make life easier. Here is some example code to get started:
+//
+// log := log4go.NewLogger()
+// log.AddFilter("stdout", log4go.DEBUG, log4go.NewConsoleLogWriter())
+// log.AddFilter("log",    log4go.FINE,  log4go.NewFileLogWriter("example.log", true))
+// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
+//
+// The first two lines can be combined with the utility NewDefaultLogger:
+//
+// log := log4go.NewDefaultLogger(log4go.DEBUG)
+// log.AddFilter("log",    log4go.FINE,  log4go.NewFileLogWriter("example.log", true))
+// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
+//
+// Usage notes:
+// - The ConsoleLogWriter does not display the source of the message to standard
+//   output, but the FileLogWriter does.
+// - The utility functions (Info, Debug, Warn, etc) derive their source from the
+//   calling function, and this incurs extra overhead.
+//
+// Changes from 2.0:
+// - The external interface has remained mostly stable, but a lot of the
+//   internals have been changed, so if you depended on any of this or created
+//   your own LogWriter, then you will probably have to update your code.  In
+//   particular, Logger is now a map and ConsoleLogWriter is now a channel
+//   behind-the-scenes, and the LogWrite method no longer has return values.
+//
+// Future work: (please let me know if you think I should work on any of these particularly)
+// - Log file rotation
+// - Logging configuration files ala log4j
+// - Have the ability to remove filters?
+// - Have GetInfoChannel, GetDebugChannel, etc return a chan string that allows
+//   for another method of logging
+// - Add an XML filter type

-// Package lru provides three different LRU caches of varying sophistication.
-//
-// Cache is a simple LRU cache. It is based on the
-// LRU implementation in groupcache:
-// https://github.com/golang/groupcache/tree/master/lru
-//
-// TwoQueueCache tracks frequently used and recently used entries separately.
-// This avoids a burst of accesses from taking out frequently used entries,
-// at the cost of about 2x computational overhead and some extra bookkeeping.
-//
-// ARCCache is an adaptive replacement cache. It tracks recent evictions as
-// well as recent usage in both the frequent and recent caches. Its
-// computational overhead is comparable to TwoQueueCache, but the memory
-// overhead is linear with the size of the cache.
-//
-// ARC has been patented by IBM, so do not use it if that is problematic for
-// your program.
-//
-// All caches in this package take locks while operating, and are therefore
-// thread-safe for consumers.
