## Trace debug commands

The `cmd` directory contains helpful tools for debugging traces.

* `gotraceraw` parses traces without validation.
  It can produce a text version of the trace wire format, or convert
  the text format back into bytes.
* `gotracevalidate` parses traces and validates them.
  It performs more rigorous checks than the parser does on its own,
  which helps for debugging the parser as well.
