checknr - check nroff and troff input files; report possible


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


     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 example,
           the  .TS  and  .TE  macros  which  must always come in

     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


     -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
           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 .ES, use `-a.BS.ES'

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

     There is no way to define a one-character macro  name  using
     the -a option.
