Test names are defined as the name of the `.go` file that generates the
trace, but with the `.go` extension removed.

## Trace test programs

The trace test programs in the `testprog` directory generate traces to
stdout.
Otherwise they're just normal programs.

## Trace debug commands

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