 **that** text.  Otherwise use `think()` instead.
 
 If you want to make your script "user-friendly" (like babbling about
-what it's doing), consider setting `FFOO_VERBOSE` to true in header of
+what it's doing), consider setting `SHELLFU_VERBOSE` to true in header of
 your script (and implementing `-q|--quiet` to tun it off).
