Avoiding substitution
=====================

   Keyword substitution has its disadvantages.  Sometimes you might
want the literal text string `$Author$' to appear inside a file without
RCS 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 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.
