Environment Variables used by CIAO

• CIAO_DEBUG_LEVEL: An interger value accessible using CIAO::debug_level() call. Currently, CIAO follow the following usage conventions:
  
  
  • 20 < debug_level ≤ 20: Generate CIAO internal debug messages
  • 10 < debug_level ≤ 20: Generate CIAO tools debug messages
  • 0 < debug_level ≤ 10: Generate component-level debug messages

• CIAO_DUMP_SAMPLE_HISTORY: This environment variable was added for lack of component configuration support. Set it to 1 to turn on the dumping of performance samples to stdout in some performance test components.
