12.3 Avoiding substitution
Keyword substitution has its disadvantages. Sometimes
you might want the literal text string
`$Author$' to appear inside a file without
CVS interpreting it as a keyword and expanding it
into something like `$Author: ceder $'.
There is unfortunately no way to selectively turn off
keyword substitution. You can use `-ko'
(see section Substitution modes) to turn off keyword
substitution entirely.
In many cases you can avoid using keywords in
the source, even though they appear in the final
product. For example, the source for this manual
contains `$@asis{}Author$' whenever the text
`$Author$' should appear. In nroff
and troff you can embed the null-character
\& inside the keyword for a similar effect.
