==========================================================================
By default, gp will be installed in $dflt/bin, manual pages under
  $dflt/man, etc..., with $dflt as prefix for all installation directories.
  If you wish to have binaries under /bin but manual pages under
  /usr/local/man, that's ok: you will be prompted separately for each of the
  installation directories, the prefix being only used to set the defaults.
  (You will be prompted before the actual installation is done.)
The names of executables and libraries contain their version number $version.
  A symbolic link to gp or libpari.[a/so] will point to the most recent
  installation of GP/PARI.
