    CAL_DISP: (Fortran Program) This program calculates the phase velocity dispersion of surface waves.
    EZXPLOT: (Fortran/C Program) Set of subroutines allows a fortran programer to use x11 graphical interface.
    PSPLOT: (Fortran Program) Set of subroutines allows a fortran programer to plot postscript files.
    C and Fortran: This code-makefile gives a quick example of how to use a fortran subroutine with a C program or a C function with a fortran program.
    TRACE.VIS This code/program visually traces rays through a layered earth model. It is interactive, allowing the user to select the wave and plot the rays in different colors. Plots are to the screen through X windows (using OSX protocals). There is also an option to output to a postscript file.
