`checkfun`	Subroutines for checking validity of the input function
`graph`	Plotting graph of the potential
`anharm1`	Calculation of pert. theory coefficients (Mathematica)
`anharm.for`	Calculation of pert. theory coefficients (Fortran)
`cplot`	Displaying coefficients graphically
`allowed1`	Description of allowed functions
`allfunct`	List of all allowed and disallowed functions
