CHECKNR(1)							    CHECKNR(1)

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.	Delimiters 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 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

       The -c option defines commands  which  would  otherwise	be  complained
       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.	 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.

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.
