zeroinstall/__init__.py

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