Installs one or more PEAR packages.  You can specify a package to
install in four ways:

"Package-1.0.tgz" : installs from a local file

"http://example.com/Package-1.0.tgz" : installs from
anywhere on the net.

"package.xml" : installs the package described in
package.xml.  Useful for testing, or for wrapping a PEAR package in
another package manager such as RPM.

"Package" : queries your configured server
({config master_server}) and downloads the newest package with
the preferred quality/state ({config preferred_state}).

More than one package may be specified at once.  It is ok to mix these
four ways of specifying packages.

upgrade anyway).
