+(i.e. those not called as methods of a specific

-      D sources can be compiled file-by-file as C and C++ source are, and
-      D is integrated into the &scons; Object and Program builders for
-      this model of build. D codes can though do whole source
-      meta-programming (some of the testing frameworks do this). For this
-      it is imperative that all sources are compiled and linked in a single call of
-      the D compiler. This builder serves that purpose.

-      This command will compile the modules mod_a, mod_b, and mod_c in a

-      will not.
