ISMann2dig also creates a dig_att file containing the label information 'stripped' from the ISM annotation file. However, the user must run v.support (or v.import option 4) on the output file created by ISMann2dig to create a dig_plus file containing the file topology, before using the output file in v.digit.
If the user simply types ISMann2dig without specifying parameter values on the command line, the program will prompt the user to enter these.
GRASS does not currently support multiple line styles and colors, but any existing text labels in the annotation data file are used to identify unique attributes for dig vectors.
