-@findex replace-regexp-in-region
-  If it's more convenient, you can also use the
-@code{replace-regexp-in-region}, which does something similar to the
-loop above, but is optionally delimited to a specific region (and
-doesn't change point).  Furthermore, it does the searches
-case-sensitively, and performs the replacements without changing case
-in the replacement.
+  It may be more convenient to limit the replacements to a specific
+region.  The function @code{replace-regexp-in-region} does that.

+@defun replace-regexp-in-region regexp replacement &optional start end
+This function replaces all the occurrences of @var{regexp} with
+@var{replacement} in the region of buffer text between @var{start} and
+@var{end}; @var{start} defaults to position of point, and @var{end}
+defaults to the last accessible position of the buffer.  The search
+for @var{regexp} is case-sensitive, and @var{replacement} is inserted
+without changing its letter-case.  The @var{replacement} string can
+use the same special elements starting with @samp{\} as
+@code{replace-match} does.  The function returns the number of
+replaced occurrences, or @code{nil} if @var{regexp} is not found.  The
+function preserves the position of point.
 
 @example
 (replace-regexp-in-region "foo[ \t]+bar" "foobar")

-@findex replace-string-in-region
-  There's also @code{replace-string-in-region}, which works along the
-same lines, but searches for literal strings instead.
+@defun replace-string-in-region string replacement &optional start end
+  This function works similarly to @code{replace-regexp-in-region},
+but searches for, and replaces, literal @var{string}s instead of
+regular expressions.
+@end defun
 
   Emacs also has special functions for replacing matches in a string.
