This is useful if you # want to try out the system, running test suites, etc, before doing the # real install using the configuration you have set up using `configure'. # A similar thing can be done by overriding `prefix' if only default # installation directories are used. However, the installation can get # sprawled out all over the place if the user use `--bindir', `--libdir', # etc, and it is possible that `prefix' wont have any effect at all.
