First, throw away ".zo" versions of your program—at least for the modules or files that should be instrumented for error reporting or profiling.


After starting errortrace in one of these ways, when an exception occurs, the exception handler prints something like a stack trace with most recent contexts first.

The errortrace module is strange: Don’t import it into another module. Instead, the errortrace module is meant to be invoked from the top-level, so that it can install an evaluation handler, exception handler, etc.

To reuse parts of the code of errortrace, import errortrace/errortrace-lib. That library contains all of the bindings described here, but does not set the compilation handler or the error display handler.
