Description:

Originally part of the 1.4.0 new features, remote installation
through FTP is now its own package. This package adds the commands
"remote-install" "remote-upgrade" "remote-uninstall" and
"remote-upgrade-all" to the PEAR core.

To take advantage, you must have a config file on the remote ftp
server and full access to the server to create and remove files.
The config-create command can be used to get started, and the
remote_config configuration variable is set to the full URL as
Source0: http://download.pear.php.net/package/PEAR_RemoteInstaller-0.3.1.tar.bz2
in "ftp://ftp.example.com/path/to/pear.ini"

After this is done, install/upgrade as normal using the remote*
commands as if they were local.
