-
-  GOALS
-
-  o Enable a "pull" interface. The application that uses libcurl decides where
-    and when to ask libcurl to get/send data.
-
-  o Enable multiple simultaneous transfers in the same thread without making it
-    complicated for the application.
-
-  o Enable the application to select() on its own file descriptors and curl's
-    file descriptors simultaneous easily.
-

- * This header file should not really need to include "curl.h" since curl.h
- * itself includes this file and we expect user applications to do #include
- * <curl/curl.h> without the need for especially including multi.h.
- *
- * For some reason we added this include here at one point, and rather than to
- * break existing (wrongly written) libcurl applications, we leave it as-is
