deprecate the MSG and SimDag APIs. Everything that you can do in
SimGrid will be possible in S4U.
-@warning <b>S4U is not ready for public use yet</b>. You should not go
- that path unless you know what you are doing. If unsure,
- proceed to @ref MSG_API instead.
+@warning <b>S4U is not as rock stable as the rest of SimGrid yet</b>.
+ You are really welcome to test it, but be warned that the API
+ may change without notice between releases. This is however
+ the way to go if you want to create a new long-term project.
+ If you want to play safe, proceed to @ref MSG_API instead.
Unsurprisingly, the S4U interface matches the concepts presented in
@ref starting_components "the introduction". You should read this page
