+---[ (0) README ]------------------------------------------
|   Installing:
|      Using a terminal, go to your OCCA directory
|         You should see: this README, include, src, lib
|         Set OCCA_DIR (check (2) below)
|         Type "make" to compile libocca
|
|   Running Examples:  (After compiling libocca)
|      Setup your LD_LIBRARY PATH (check (3) below)
|      cd examples/addVectors
|      make
|      ./main (C++), ./main_c (C), python main.py, etc
|
|   Further options can be seen in (4-7)
|
|   OS Status:
|      Linux and OSX are fully supported
|      Windows is partially supported
|        - Code is up-to-date for windows
|        - Missing compilation project/scripts
|        - Visual Studio project is out of date
|
|  OKL Status:
|    Supports most of C (send bugs =))
|    Preprocessor is missing variadic functions
|
|  OFL Status:
|    Currently only supports a subset of Fortran:
|       - integer, real, character, logical, double precision
|       - function, subroutine
|       - DO, WHILE, IF, IF ELSE, ELSE
