summary: etrace traces programs for debugging or performance analysis
description: |
  etrace is a utility like strace or ltrace which uses ptrace to follow 
  programs executed by a main program for performance and debugging analysis. It
  also supports limited tracing of file accesses for analyzing what files a
  program accesses during it's execution.
