    NAME
         checknr - check nroff/troff files

    SYNOPSIS
         checknr [ -s ] [ -f ] [ -a.x1.y1.x2.y2. ... .xn.yn ] [
         -c.x1.x2.x3 ... .xn ] [ file ...  ]

    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.  Delimeters
         checked are:

         (1)  Font changes using \fx ... \fP.

         (2)  Size changes using \sx ... \s0.

         (3)  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(7) and me(7) macro packages.

         Additional pairs of macros can be added to the list using
         the -a option.  This must be followed by groups of six char-
         acters, each group defining 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

         The -c option defines commands which would otherwise be com-
         plained about as undefined.

         The -f option requests checknr to ignore \f font changes.

         The -s option requests checknr to ignore \s size changes.

         Checknr is intended to be used on documents that are
         prepared with checknr in mind, much the same as lint. It
         expects a certain document writing style for \f and \s com-
         mands, 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.

    DIAGNOSTICS
         Complaints about unmatched delimiters.
         Complaints about unrecognized commands.
         Various complaints about the syntax of commands.

    BUGS
         There is no way to define a 1 character macro name using -a.
         Does not correctly recognize certain reasonable constructs,
         such as conditionals.
