Next, you should install the package locally by running: pear install <file> (file is the tarball you just created). This is done to ensure that the package definition file is not only valid but also contains valid information. You should manually check that every file is installed in the right place. If your package contains test scripts, which is highly recommended, you should run them.
If anything fails at this stage, correct it and re-package and re-test. When everything seems OK, proceed.
