+====== SOM ======
+=====  Introduction =====
+SOM (Sequential Object Monitors) is a model for concurrent programming based on a thread-less scheduler. SOM makes it easier to develop concurrent programs because:
+  *SOM enforces a sequential view on multi-threaded program by ensuring individual methods are always run-to-completion, and
+  * SOM makes it possible to separate the concurrency concern from the base application.
+Furthermore, SOM is efficient and scalable: it is based on collaborative scheduling in order to minimize context switches.
+**Note: SOM is now implemented on top of [[POM]], a more generic concurrency abstraction.**
+=====  Credits =====
+This work is being developed in the INRIA-Conicyt ProXiMoS and OSCAR projects between the INRIA Sophia Antipolis (France) and the University of Chile (Chile).
+SOM has been designed by Denis Caromel, Luis Mateu and Éric Tanter.
+The SOM Plugin has been implemented, and is maintained, by  Éric Tanter and Luis Mateu.
+=====  Download =====
+SOM is now part of [[POM]] and can be obtained via the POM download.
+=====  Usage =====
+The SOM plugin handles the -som tag, which should indicate file(s) containing SOM declarations. For instance, the following:
+<code>
+ schedule: Buffer with: BufferScheduler
+</code>
+declares that instances of Buffer will be scheduled with BufferScheduler objects. If this declaration is written if a file buffer.som then the following runs Reflex appropriately:
+<code>
+java reflex.Run --use som.jar -som buffer.som MyApp
+</code>

+The complete distribution also includes the benchmarks used in the ECOOP paper, thereby giving a simple example of application.
