 * Testing
-  + Run command `make check` to test all the programs available in folders
-    `test` and `examples` in parallel on 4 MPI processes.
-  + In addition, command `make ptests` runs the same tests but using 3, 4, and
-    8 MPI processes.
-  + To run any individual programs in folders `test` and `examples`, use
-    command below. For example,
-    ```sh
-    mpiexec -n [num_process] python examples/create_open.py [output_dir]
-    ```
-    * The optional `output_dir` argument is the folder for storing the output
-      files created by the programs The default is the current folder.
