checknr(1)						      General Commands Manual							checknr(1)

Name
       checknr - check nroff/troff files

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

Description
       The  command  checks  a	list of or input files for certain kinds of errors involving mismatched opening and closing delimiters and unknown
       commands.  If no files are specified, checks the standard input.  Delimiters checked are:

       5      Font changes using fx ... fP.

	      Size changes using sx ... s0.

	      Macros that come in open ... close forms, for example, the .TS and .TE macros which must always come in pairs.

       The command knows about the and macro packages.

       The command is intended to be used on documents that are prepared with in mind, much the same as 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 Since it is probably better to use the fP and s0 forms anyway, you should think of this as a con-
       tribution to your document preparation style.

Options
       -a   Allows additional pairs of macros to be added to the list.	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.

       -c   Defines commands otherwise complained about as undefined.

       -f   Ignores f font changes.

       -s   Ignores s size changes.

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

Diagnostics
       Complaints about unmatched delimiters.

       Complaints about unrecognized commands.

       Various complaints about the syntax of commands.
