+package codec
+
+// This file sets up the variables used, including testInitFns.
+// Each file should add initialization that should be performed
+// after flags are parsed.
+//
+// init is a multi-step process:
+//   - setup vars (handled by init functions in each file)
+//   - parse flags
+//   - setup derived vars (handled by pre-init registered functions - registered in init function)
+//   - post init (handled by post-init registered functions - registered in init function)
+// This way, no one has to manage carefully control the initialization
+// using file names, etc.
+//
+// Tests which require external dependencies need the -tag=x parameter.
+// They should be run as:
+//    go test -tags=x -run=. <other parameters ...>
+// Benchmarks should also take this parameter, to include the sereal, xdr, etc.
+// To run against codecgen, etc, make sure you pass extra parameters.
+// Example usage:
+//    go test "-tags=x codecgen unsafe" -bench=. <other parameters ...>
+//
+// To fully test everything:
+//    go test -tags=x -benchtime=100ms -tv -bg -bi  -brw -bu -v -run=. -bench=.
+
+// Handling flags
+// codec_test.go will define a set of global flags for testing, including:
+//   - Use Reset
+//   - Use IO reader/writer (vs direct bytes)
+//   - Set Canonical
+//   - Set InternStrings
+//   - Use Symbols
+//
+// This way, we can test them all by running same set of tests with a different
+// set of flags.
+//
+// Following this, all the benchmarks will utilize flags set by codec_test.go
+// and will not redefine these "global" flags.
