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

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


DESCRIPTION
     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. Delimiters
     checked are:

         o    Font changes using \fx ... \fP.

         o    Size changes using \sx ... \s0.

         o    Macros that come in open ... close forms, for exam-
              ple,  the .TS and .TE macros which must always come
              in pairs.


     checknr knows about the ms(5) and me(5) macro packages.


     checknr is  intended  to  be  used  on  documents  that  are
     prepared  with  checknr in mind.  It expects a certain docu-
     ment 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  prac-
     tice will produce complaints from checknr. Since it is prob-
     ably better to use the \fP and \s0 forms anyway, you  should
     think of this as a contribution to your document preparation
     style.

OPTIONS
     -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  .DE)  that
                             should  be checked for balance.  The
                             -a option must be followed by groups

                             of six characters, each group defin-
                             ing a pair of macros. The six  char-
                             acters are a period, the first macro
                             name, another period, and the second
                             macro name. For example, to define a
                             pair .BS and .ES, use `-a.BS.ES'
