  17-Nov-1999 WPS moved emcGetArgs from emcglb.c to this file.
  10-Nov-1999 WPS added -host  and -queryhost option to emcGetArgs.
  16-Sep-1999  FMP took out errors in emcGetArgs for unrecognized args
  21-Jul-1999  FMP removed -d from emcGetArgs() since DEBUG is now in
  ini file; added EMC_NMLFILE in emcGetArgs()
  6-Jul-1998  FMP added EMC_DEBUG, emcGetArgs()
