#install_package(name, version) ⇒ Object Also known as: upgrade_package

The install/update action needs to be tested with various kinds of packages on AIX viz. packages with or without licensing file dependencies, packages with dependencies on other packages which will help to test additional options of installp. So far, the code has been tested only with standalone packages.
