23/// The FDRTraceWriter allows us to hand-craft an XRay Flight Data Recorder
24/// (FDR) mode log file. This is used primarily for testing, generating
25/// sequences of FDR records that can be read/processed. It can also be used to
26/// generate various kinds of execution traces without using the XRay runtime.
27/// Note that this writer does not do any validation, but uses the types of
28/// records defined in the FDRRecords.h file.
