CHECKNR(1)CHECKNR(1)NAMEchecknr - check nroff/troff files
SYNOPSISchecknr [ -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.

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.
