Description
The init-only variables can only be set via sdf's -D option or via the init macro on the top line of a file.
The processing variables control the processing of SDF text before it is passed to a format driver for conversion.
DEFAULT_TAB_SIZE is used when tabs are converted to spaces within SDF files.
