Description:

PEAR_PackageUpdate (PPU) is designed to allow developers to easily
include auto updating features for other packages and PEAR installable
applications. PPU will check to see if a new version of a package is
available and then ask the user if they would like to update the
package. PPU uses PEAR to communicate with the channel server and to
execute the update.

PPU allows the end user to take some control over when they are
notified about new releases. The PPU Preferences allow a user to tell
PPU not to ask about certain types of releases (bug fixes, minor
releases, etc.), not to ask about certain release states (devel,
alpha, etc.), not to ask until the next release or not to ask again.

PPU is just an engine for package updating. It should not be used
directly. Instead one of the driver packages such as
PEAR_PackageUpdate_Gtk2 should be used depending on the application or
other package.

In PEAR status of this package is: beta.
