// This file implements a handle way of adding debugging information to your
|
|
// code, without it being enabled all of the time, and without having to add
|
|
// command line options to enable it.
|
|
//
|
|
// In particular, just wrap your code with the DEBUG() macro, and it will be
|
|
// enabled automatically if you specify '-debug' on the command-line.
|
|
// Alternatively, you can also use the SET_DEBUG_TYPE("foo") macro to specify
|
|
// that your debug code belongs to class "foo". Then, on the command line, you
|
|
// can specify '-debug-only=foo' to enable JUST the debug information for the
|
|
// foo class.
|
|
//
|
|
// When compiling in release mode, the -debug-* options and all code in DEBUG()
|
|
// statements disappears, so it does not effect the runtime of the code.
