+== What do we want ? ==
+
+We want a tool which can build a complete virtual prototype (aka SystemC simulator) from:
+ * a topcell provided by user
+ * a list of parametrable components, and their parameters
+
+Therefore we need the following features:
+ * Component indexation in the library tree
+ * Parametrization of source files
+ * Build of all these files
+
+We also want to be able to compile all these with different SystemC implementation
+and different compilation modes (debug, release, profiling, …) without having
+to change build files.
+
+As virtual prototypes
+may be huge but users always use the same parameters, we would like the
+following additional features:
+ * Parallel compilation
+ * Object caching (ccache could be an option)
+
+As we speak about C++, parametrization of source files uses templated code.

+There is no build tool known out there which does object caching and
 template instantiation at the same time. Even if current build tools
 may be enhanced to do the job, this is not an easy task.
 Moreover, resulting code would be a kludge.
 This is all about flexibility, and user-input readability.

 Soclib-cc has been implemented as a `make` wrapper before,
