    File:       oidParser.h

        Contains:   parse an Intel-style OID, with the assistance of dumpasn1.cfg

                        The config file is looked for in the following locations:

                        current working directory (.)

                        parent directory (..)

                        The directory specified by the environment variable LOCAL_BUILD_DIR

                        OidParser will still work if the config file is not found, but OIDs will be

                        dispayed in raw hex format.
