Package pdebug provides tools to produce debug logs the way the author (Daisuke Maki a.k.a. lestrrat) likes. All of the functions are no-ops unless you compile with the `-tags debug` option. When you compile your program with `-tags debug`, no trace is displayed, but the code enclosed within `if pdebug.Enabled { ... }` is compiled in. To show the debug trace, set the PDEBUG_TRACE environment variable to true (or 1, or whatever `strconv.ParseBool` parses to true) If you want to show the debug trace regardless of an environment variable, for example, perhaps while you are debugging or running tests, use the `-tags debug0` build tag instead. This will enable the debug trace forcefully
