  Agnes added a direct estimation of mortality (without the need of
  computing period prevalence and differential mortality). Thus here
  is version 0.97a which has been distributed to some people at
  REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of
  mortality using covariates is not done today. Estimating direct
  mortality is a very different process because it doesn't need
  interpolation because it is easy to get the lx from the force of
  the mortality mux in the simplest case as for a Gompertz (log mux
  = a + b*x . But we have been able to incorporate the new code
  within former imach program (0.96d) without deteriorating too much
  the understanding of the program.

Gnuplot is now installed in the same directory (on Windows) as imach.
Thus the full path of gnuplot is executed in order to access the
current version.
