+formatted according to Italian style conventions.  It is highly configurable,
+and its modular structure provides you with building blocks of increasing
+level, by means of which you can compose a large variety of letters.  It is
+also possible to write letters divided into sections and paragraphs, to
+include floating figures and tables, and to have the relevant indexes compiled
+automatically.  A single input file can contain several letters, and each
+letter will have its own table of contents, etc., independent from the other
+ones.")
