+Installs one or more PEAR packages.  You can specify a package to

+
+&quot;http://example.com/Package-1.0.tgz&quot; : installs from
+anywhere on the net.
+
+&quot;package.xml&quot; : installs the package described in
+package.xml.  Useful for testing, or for wrapping a PEAR package in
+another package manager such as RPM.
+
+&quot;Package[-version/state][.tar]&quot; : queries your default channel&#039;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 &quot;Package-1.1,&quot; to retrieve
+Package state beta, use &quot;Package-beta.&quot;  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
+&quot;channel/Package&quot;
+
+More than one package may be specified at once.  It is ok to mix these
+four ways of specifying packages.

+ - more than one extsrcrelease or zendextsrcrelease
