13.3 Extending installation
It is possible to extend this mechanism by defining an
install-data-local target. If these
targets exist, they will be run at `make install' time. These
rules can do almost anything; care is required.
Automake also supports two install hooks,
install-data-hook. These hooks are run after all other install
rules of the appropriate type, exec or data, have completed. So, for
instance, it is possible to perform post-installation modifications
using an install hook.
