-         "     --bem/--fem/--fembem: Numerical model (bem is dense, fem is sparse). Default: bem.\n"
          "     -nbpts: Number of unknowns of the global linear system. Default: 16000 (can be in floating point notation, like 1.2e4).\n"
          "     -nbrhs: Number of right-hand sides of the global linear system. Default: 1.\n"
          "     -s/-d/-c/-z: Scalar type of the computation (real computation uses 1/R kernel in BEM, complex computation uses oscillatory exp(ikr)/r kernel). Default: z.\n"
-         "     -v: Verbose mode, to display values of data (extremely verbose). Default is OFF.\n"
-         "     --new-rhs/--no-new-rhs: Use (or not) new way to compute RHS (old way was producing low rank RHS). Default is ON.\n"
          "     -lambda: Wavelength (for oscillatory kernels). Mutually exclusive with -ptsperlambda. Default lambda is set with 10 points per wavelength.\n"
          "     -ptsperlambda: Points per wavelength on the main cylinder (for oscillatory kernels). Default: 10.\n"
          "     --write-mesh: Write a VTK file 'mesh.vtu' of the mesh. Default is OFF.\n"
