Source Code for Package zeroinstall

 1  """ 
 2  The Python implementation of the Zero Install injector is divided into five sub-packages: 
 3   
 4   - L{zeroinstall.cmd} contains one module for each 0install sub-command (providing the shell-scripting interface) 
 5   - L{zeroinstall.injector} contains most of the interesting stuff for managing feeds, keys and downloads and for selecting versions 
 6   - L{zeroinstall.zerostore} contains low-level code for handling the implementation cache (where unpacked packages are stored) 
 7   - L{zeroinstall.gtkui} contains code for making GTK user-interfaces 
 8   - L{zeroinstall.support} contains helper code (not really specific to Zero Install)
