  19  * dumpasn1.cfg.
  20  *
  21  * The config file is looked for in the following locations:
  22  *
  23  *  current working directory (.)
  24  *  parent directory (..)
  25  *  The directory specified by the environment variable LOCAL_BUILD_DIR
  26  *
  27  * OidParser will still work if the config file is not found, but OIDs
  28  * will be dispayed in raw hex format.
