-Modify .soclib/global.conf as the following:
+
+''Note: The following information is taken from the [http://www.soclib.fr/trac/dev/wiki/SoclibCc/SoclibConf soclib] trac.''
+
+SoCLib's configuration file is used by `soclib-cc` to find your tools paths. You may override:
+
+ * `libraries`: SystemC implementation to use (its paths, ...), tlm, ...
+ * `toolchain`: Compiler and compiler flags
+ * `build env`: toolchain, libraries and other flags (where objects reside, ...) 
+
+Let's suppose we want to override SystemC's path, we can write the following `~/.soclib/global.conf`:
 
 {{{
-config.systemcass = Config(
-       base = config.systemc,
-       dir = "/path/to/systemcass/",
-       libs = ["-Wl,-rpath,%(libdir)s", "-L%(libdir)s", "-lsystemc", "-ldl"],
-       )
+#!python
+config.libsystemc_22 = Library(
+        parent = config.systemc,
+        dir = "/home/me/tools/systemc/2.2"
+        )
 
-config.use_systemcass = Config(
-       base = config.default,
-       systemc = config.systemcass,
-       repos = config.default.repos + "/systemcass",
-       )
+config.foo = BuildEnv(
+        parent = config.build_env,
+        libraries = [config.libsystemc_22],
+        )
+
+config.default = config.foo
 }}}
+
+Now let's suppose we would like to add another configuration where we use !SystemCass. We don't want compiled objects to mix-up, so we'll set another repository for built files.
+
+{{{
+#!python
+config.libsystemcass = Library(
+        parent = config.systemc,
+        dir = "/home/me/tools/systemc/cass",
+        libs = config.systemc.libs + ["-Wl,-rpath,%(libdir)s", "-ldl", "-fopenmp"],
+        )
+
+config.systemcass = BuildEnv(
+        parent = config.default,
+        repos = "repos/systemcass_objs",
+        libraries = [config.libsystemcass],
+        )
+}}}
+
+Now if we want to compile a platform with !SystemCass, the only thing to do is to tell it to `soclib-cc`:
+
+{{{
+$ soclib-cc -t systemcass
+}}}
+
+The argument after -t is the configuration name, attribute set to config in this line:
+
+{{{
+config.systemcass = BuildEnv( ....
+}}}
+
+
+The only configuration names that can be passed to `-t` are the ones associated to `BuildEnvs`.
