+Description: install packages using the apt protocol - common data
+ AptUrl is a simple graphical application that takes an URL (which follows the
+ apt-protocol) as a command line option, parses it and carries out the
+ operations that the URL describes (that is, it asks the user if he wants the
+ indicated packages to be installed and if the answer is positive does so for
+ him).
+ .
+ This package contains the common data shared between the frontends.
