-\fIage\fP describes what kind of struct this is. It is always 0 now. In a
-future libcurl, if this struct changes, this age counter may be increased, and
-then the struct for number 1 will look different (except for this first struct
-field).
+\fIage\fP describes what age of this struct this is. The number depends on how
+new libcurl you're using. You are however guaranteed to get a struct that you
+have a matching struct for in the header, as you tell libcurl your "age" with
+the input argument.
 
 \fIversion\fP is just an ascii string for the libcurl version.
