.Sh DESCRIPTION
.Nm Style
analyzes the surface characteristics of the writing style
of a document.
It reports on readability, sentence length and
structure, word length and usage, verb type, and sentence openers.
Because

.Xr deroff
before looking at the text, formatting
header files should be included as part of the input.

.It Fl ml
The flag
.Fl ml ,
which causes

to skip lists, should be used if the document contains many lists of
non-sentences.
