CW (l)
HINTS
CW(l)
The options are:
-lxx The one- or two-character string xx becomes the left delimiter;
if xx is omitted, the left delimiter becomes
undefined, which it is initially.
-rxx Same for the right delimiter. The left and right delimiters
may (but need not) be different.
-fn The CW font is mounted in font position n; acceptable
values for n are 1, 2, and 3 (default is 3, replacing the
bold font). This option is only useful at the beginning of
a document.
-t Turn transparent mode off.
+t Turn transparent mode on (this is the initial default).
-d Print current option settings on file descriptor 2 in the
form of troff comment lines. This option is meant for
debugging.
Cw reads the standard input when no files are specified (or when
- is specified as the last argument), so it can be used as a filter.
Typical usage is:
cw files I troff ...
Checkcw checks that left and right delimiters, as well as the
.CW j.CN pairs, are properly balanced. It prints out all offending
lines.
Typical definitions of the .CW and .CN macros meant to be used
with the mm(5) macro package:
.de CW
.DS I
.ps 9
.vs 10.5p
.ta 16m/3u 32m/3u 48m/3u 64m/3u 80m/3u 96m/3u ...
. de CN
.ta .5i 1i 1.5i 2i 2.5i 3i ...
. vs
.ps
.DE
At the very least, the .CW macro should invoke the troff no-fill
(.nf) mode.
When set in running text, the CW font is meant to be set in the
same point size as the rest of the text. In displayed matter, on
the other hand, it can often be profitably set one point smaller
than the prevailing point size (the displayed definitions of .CW
and .CN above are one point smaller than the running text on this
page). The CW font is sized so that, when it is set in 9-point,
there are 12 characters per inch.
