# tazpkg-notify - part of TazPkg
# Notification icon for TazPkg packages

# Recharging pkgs list can be done automatically at boot, so notify users
# if some updates are available. Also notify users if the packages list is too
# old and out-of-date or if no packages list found. This script should
# be run by the WM autostart script or ~/.xsession and needs a systray to
# sit in like in LXpanel or Tint2.
