NAME
      checknr - check nroff and troff input files; report possible errors

SYNOPSIS
      /usr/ucb/checknr [ -fs ] [ -a .x1 .y1 .x2 .y2 . . .  .xn .yn ]
                             [ -c .x1 .x2 .x3 . . .  .xn ] [ filename . . . ]

DESCRIPTION
      The checknr command checks a list of nroff or troff 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.  Delimiters checked are:

            ⊕  Font changes using \fx . . . \fP.

            ⊕  Size changes using \sx . . . \s0.

            ⊕  Macros that come in open . . .  close forms, for example, the
               .TS and .TE macros which must always come in pairs.

      checknr knows about the ms and me macro packages.

      checknr is intended to be used on documents that are prepared with
      checknr in mind.  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.

      The following options are available:

      -f    Ignore \f font changes.

      -s    Ignore \s size changes.

      -a .x1 .y1 . . .
            Add pairs of macros to the list.  The pairs of macros are assumed
            to be those (such as .DS and that should be checked for balance.
            The -a option must be followed by groups of six characters, each
            group defining a pair of macros. The six characters are a period,
            the first macro name, another period, and the second macro name.
            For example, to define a pair .BS and use -a.BS.ES

      -c .x1 . . .
            Define commands which checknr would otherwise complain about as
            undefined.
