This is utility to split input text into paragraphs and justify it, e.g. format it to become text with width N (20 - 120) characters aligned to the right and the left edge. Line width should be increased by adding spaces - one by one, starting from the right. The end of the paragraph is a string that ends in the corresponding punctuation. New paragraphs should indent four spaces. Paragraph of a single line less than half of N - is the title and its justify not needed.
