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[-version/state][.tar]" : queries your default channel\'s server
({config master_server}) and downloads the newest package with
the preferred quality/state ({config preferred_state}).

To retrieve Package version 1.1, use "Package-1.1," to retrieve
Package state beta, use "Package-beta."  To retrieve an uncompressed
file, append .tar (make sure there is no file by the same name first)

To download a package from another channel, prefix with the channel name like
"channel/Package"

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

Upgrades one or more PEAR packages.  See documentation for the

When upgrading, your package will be updated if the provided new
package has a higher version number (use the -f option if you need to
upgrade anyway).

More than one package may be specified at once.
