    parenthesized
  o entries may be grouped according to category, with a category header 
    (different from a version header) starting at the beginning of a line
  o entries are written as itemize-type lists, using one of o, *, - or + as 
    item tag. Entries must be indented, and ideally use a common indentation 
    for the item texts
