There are good reasons why the different wrapper module filenames cannot be the same (indeed, they used to be the same, but it didn't work).

1. Both Python and Lua have strict naming requirements for wrapper modules -- but the naming requirements are not the same;
   therefore, the Python and Lua wrappers simply can't go into the same file.

2. Some people want wrappers for one language, other people want wrappers for another language. 
   Under these circumstances, it is easier to maintain the build by separating the modules.

3. In some of the builds (e.g. Microsoft Visual Studio) code using the standard C++ library cannot be exported;
   in those builds, libraries using the standard C++ library must be static libraries (e.g. csnd, CsoundAC).

4. So, I have factored out the build into the following logical layers:

   +---------------------+--------------------+-------------------+
   | SWIG Python module  |  SWIG Java module  |  SWIG Lua module  |
   +---------------------+--------------------+-------------------+
   | csnd library (static in some builds, shared in other builds) |
   +--------------------------------------------------------------+
   |                    Csound API shared library                 |
   +--------------------------------------------------------------+

Hope this helps,

Mike
