checknr checks a list of
  nroff(1) or
  troff(1) input files for certain
  kinds of errors involving mismatched opening and closing delimiters and
  unknown commands. If no files are specified, checknr
  checks the standard input.
Recognized options are:
-a-a.BS.ES’.-c-fchecknr to ignore
      ‘\f’ font changes.-s\s’ size changes.Delimiters checked are:
checknr is intended for use on documents
    that are prepared with checknr in mind, much the
    same as lint(1). It expects a
    certain document writing style for
    ‘\f’ and
    ‘\s’ commands, in that each
    ‘\fx’ must be terminated with
    ‘\fP’ and each
    ‘\sx’ must be terminated with
    ‘\s0’. While it will work to directly
    go into the next font or explicitly specify the original font or point size,
    and many existing documents actually do this, such a practice will produce
    complaints from checknr. Since it is probably better
    to use the ‘\fP’ and
    ‘\s0’ forms anyway, you should think
    of this as a contribution to your document preparation style.
checknr knows about the
    ms(7) and
    me(7) macro packages, as well as
    the macros from mdoc(7).
checknr command appeared in
  4.0BSD. Basic
  mdoc(7) support appeared in
  NetBSD 1.6.
-a.
Does not correctly recognize certain reasonable constructs, such as conditionals.
mdoc(7) macros that
    are not at the beginning of the line are not recognized. Among others, this
    results in too many ‘Unmatched Zz’
    errors.
