I would point out that the author has also made this code
available on MathSource.  The item number is 0206-738 and can be
found in the WhatsNew directory on the MathSource FTP and

0206-738: Approximate Inversion of Laplace Transform (May 17, 1994)
          Authors: Alexander Cheng
          The Laplace transform is often applied to linear partial
          differential equations to eliminate the time dimension. The
          analytical solutions thus obtained need to be inverted to the time
          domain.  This package provides the Mathematica utility for
          approximate inversion of Laplace transform.
