+Style #19
+==============================
+
+Constraints:
+
+- The problem is decomposed using some form of abstraction
+  (procedures, functions, objects, etc.)
+
+- All or some of those abstractions are physically encapsulated into
+  their own, usually pre-compiled, packages. Main program and each of
+  the packages are compiled independently. These packages are loaded
+  dynamically by the main program, usually in the beginning (but not
+  necessarily).
+
+- Main program uses functions/objects from the dynamically-loaded
+  packages, without knowing which exact implementations will be
+  used. New implementations can be used without having to adapt or
+  recompile the main program.
+
+- External specification of which packages to load. This can be done
+  by a configuration file, path conventions, user input or other
+  mechanisms for external specification of code to be linked at run
+  time.
+
+Possible names:
+
+- No commitment
+- Plugins
+- Why one when we can have many?
