"This package includes two scripts (trcinit.cmd and trcctl.cmd) that implement an interface to the OS/2 Trace Facility. These scripts are designed to make it easier to capture the specific trace data needed to analyze a problem. The scripts are generic. The tracepoints and settings needed to capture specific data are defined in a configuration file."
