There is support for simple option lists,

-I, --include          an option with both a short option and a long option

--all                  Output all.

--both                 Output both (this description is

                       quite long).

--long                 Output all day long.

--par                 This option has two paragraphs in its description.

                      This is the first.

                      This is the second.  Blank lines may be omitted between

                      options (as above) or left in (as here).

The next paragraph looks like an option list, but lacks the two-space

marker after the option. It is treated as a normal paragraph:

--foo bar baz
