The
utility 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,
checks the standard input.
The following options are available:
-a
Add additional pairs of macros to the list of known macros.
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
Define commands which would otherwise be complained about
as undefined.
-f
Request
to ignore
`\f'
font changes.
-s
Ignore
`\s'
size changes.
Delimiters checked are:
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
utility is intended for use on documents that are prepared with
in mind, much the same as
lint(1).
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 contribution to your document
preparation style.
The
utility knows about the
ms(7)
and
me(7)
macro packages.
