Automake build feature for ELPA_2011.12

ELPA version 2011.12 can now be build with automake into
a shared/static library. This should help the bundling in
linux distributions

The other versions of ELPA will be updated soon

ELPA_2011.12/INSTALL

+How to install ELPA:
+----------------------
+
+ELPA is shipped with a typical "configure" and "make" procedure. It is
+recommended to use this way to install ELPA. If you do not want to install
+ELPA as library, but to include it in your source code, you can find a 
+"Makefile.example" in ./test, to see how this is done. Please distibute then 
+all nfiles of ELPA with your code.
+
+
+The configure installation is best done in four steps
+
+1) run configure: 
+   please point to your blacs/scalapack installation and the
+   linkline with the variables "BLACS_LDFLAGS" and "BLACS_FCFLAGS". 
+   You can either specify your own builds of lapack/blacs/scalapack
+   or use specialized Vendor packages, e.g. if available you can use 
+   Intel's MKL
+
+   Please set the optimisation that you would like with the
+   variable "OPT_FCFLGS", e.g. OPT_FCFLAGS="-O3 -xAVX"
+
+   Check the available options with "configure --help". 
+   If available you can e.g. choose especially optimized elpa kernels
+   for your system.
+
+   Set the "prefix" - flag, if you wish another installation location than
+   the default "/usr/local/"
+
+
+2) run "make"
+
+3) run "make check"
+   a simple test of ELPA is done. At the moment the usage of "mpiexec"
+   is required. If this is not possible at your system, you can run the
+   binaries "test_real", "test_real2", "test_complex", and "test_complex2"
+   yourself. At the moment the tests check whether the residual and the
+   orthogonality of the found eigenvectors are lower than a threshold of
+   5e-12. If this test fails, or if you believe the threshold should be
+   even lower, please talk to us.
+
+
+4) run "make install"
+   Note that a pckconfig file for ELPA is produced
+
+How to use ELPA:
+-----------------
+Using ELPA should be quite simple. It is similiar to ScalaPack but the API
+is different. See the examples in the directory "./test". There is shown how
+to evoke ELPA from a Fortran code.
+
+If you installed ELPA with the build procedure a pk-config file is produced.
