+* test: unit tests
+* CuTest: third-party unit test framework
+* amos: third-party FORTRAN routines for special functions
+* doc: documentation (LaTeX, master thesis)
+* slides: presentation (LaTeX)

+dependencies:
+* C and Fortran compilers (tested with gcc/gfortran and icc/ifort)
+* BLAS/LAPACK for C (tested with mkl and openblas)
+* GSL (tested with version 2.5) 
+* MPI (optional, can be disabled at configure stage)
+
+build stages:
+* configure: configure options, creates Makefile from Makefile.in, 
+* make: creates binary executable
+
+example build and run:
+* CONFIGURE CC=icc FC=ifort CBLAS=mkl
+* make
