* Installation directories will be inferred from the actual location of the shared library that contains the component. * OPAL_PREFIX and other environment variables allow users to override the inferred directories. They should no longer be necessary in most cases, though. * Any directories that cannot be inferred will fall back to whatever is provided by the config installdirs component. This commit was SVN r21723.

# the actual files.
