 DESCRIPTION
 -----------
-The LTTng-UST `tracef()` API allows you to trace your application with
-the help of a simple man:printf(3)-like macro. The 'fmt' argument is
-passed directly to the 'fmt' parameter of man:vasprintf(3), as well as
-the optional parameters following 'fmt'.
+The LTTng-UST `tracef()` and `vtracef()` API allows you to trace your
+application with the help of simple man:printf(3)-like and
+man:vprintf(3)-like macros.
 
-To use `tracef()` or `vtracef()`, include `<lttng/tracef.h>` where you need it,
-and link your application with `liblttng-ust`. See the <<example,EXAMPLE>>
-section below for a complete usage example.
