-### Command line interface
-
-The package is equipped with the command line tool `tb` the usage of which reads:
-
-```
-tb [-h] [--k_points_file K_POINTS_FILE] [--xyz XYZ] 
-   [--show SHOW] [--save SAVE] 
-   [--code_name CODE_NAME] param_file
-    
-    positional arguments:
-      param_file            Path to the file in the yaml-format containing all
-                            parameters needed to run computations.
-    
-    optional arguments:
-      -h, --help            show this help message and exit
-      --k_points_file K_POINTS_FILE
-                            Path to the txt file containing coordinates of wave
-                            vectors for the band structure computations. If not
-                            specified, default values will be used.
-      --xyz XYZ             Path to the file containing atomic coordinates. If
-                            specified, it overrides the coordinates specified in
-                            the param_files.
-      --show SHOW, -S SHOW  Show figures, 0/1/2. 0 shows nothing, 1 outputs
-                            figures on screen, 2 saves figures on disk without
-                            showing.
-      --save SAVE, -s SAVE  Save results of computations on disk, 0/1.
-      --code_name CODE_NAME
-                            Code name is added to the names of all saved data
-                            files.
-```
-
-
-The results of computations will be stored in `band_structure.pkl` file in the current directory.
-This file name can be modified by specifying the parameter `--code_name`.
-
-On the computers with `mpi` functions installed, instead of `tb` one has to use its mpi-version `tbmpi`. 
-The script `tbmpi` parallelises the loop running over the wave vectors.
-This script can be used together with the command `mpirun` (below is an example generating 8 parallel processes):
-
-```
-mpirun -n 8 tbmpi --show=2 --save=1 --xyz=si.xyz --k_points=k_points.txt input.yaml 
-```
