uninstall - remove a package
Introduction
The uninstall command removes a package and accepts a list of installed packages to remove as arguments.
--plugin
Plugins (documented here) must be explicitly
uninstalled with the -p or --plugin option.
Plugins are installed into the location specified by the plugins_dir
configuration variable, which defaults to the same location that the user
configuration file is located ($HOME/.pear in unix,
<My Documents>\pear on windows).
php pyrus.phar uninstall -p PEAR2_Pyrus_Developer
--force
The --force or -f option can be used
to force uninstallation if there are errors. For instance, this can be used
to override problems in dependency validation. As such, it should be used
sparingly if at all. Better is to uninstall the packages tha depend on the
package being uninstalled.
