     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 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

     -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 bal-
                     ance.   The  -a  option  must be followed by
                     groups of six characters, each group  defin-
                     ing a pair of macros. The six characters are
                     a period,  the  first  macro  name,  another
                     period, and the second macro name. For exam-
                     ple, to define a pair .BS and  .ES,  use  `-

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

     See attributes(5) for descriptions of the  following  attri-

    |       ATTRIBUTE TYPE        |       ATTRIBUTE VALUE       |
    | Availability                | SUNWdoc                     |

     eqn(1), nroff(1), troff(1), attributes(5), me(5), ms(5)

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