Package zeroinstall

The Python implementation of the Zero Install injector is divided into four sub-packages:

zeroinstall.injector contains most of the interesting stuff for managing feeds, keys and downloads and for selecting versions
zeroinstall.zerostore contains low-level code for handling the implementation cache (where unpacked packages are stored)
zeroinstall.gtkui contains code for making GTK user-interfaces
zeroinstall.support contains helper code (not really specific to Zero Install)

Submodules

zeroinstall.alias: Support code for 0alias scripts.
zeroinstall.gtkui: GTK user interface.
- zeroinstall.gtkui.addbox: A GTK dialog which lets the user add a new application to their desktop.

- zeroinstall.gtkui.treetips: Add tooltips to a TreeView.
- zeroinstall.gtkui.trust_box: A dialog box for confirming GPG keys.
- zeroinstall.gtkui.xdgutils: Adding icons and menu items using the freedesktop.org system.
zeroinstall.helpers: Convenience routines for performing common operations.
zeroinstall.injector: Code relating to interfaces and policies.
- zeroinstall.injector.arch: Information about the current system's architecture.
- zeroinstall.injector.autopolicy: A simple non-interactive policy.
- zeroinstall.injector.background: Check for updates in a background process.
- zeroinstall.injector.cli: The 0launch command-line interface.
- zeroinstall.injector.distro: Integration with native distribution package managers.
- zeroinstall.injector.download: Handles URL downloads.
- zeroinstall.injector.fetch: Downloads feeds, keys, packages and icons.
- zeroinstall.injector.gpg: Python interface to GnuPG.

- zeroinstall.injector.model: In-memory representation of interfaces and other data structures.
- zeroinstall.injector.namespaces: Useful constants.
- zeroinstall.injector.packagekit: PackageKit integration.
- zeroinstall.injector.policy: This class brings together a solve.Solver to choose a set of implmentations, a fetch.Fetcher to download additional components, and the user's configuration settings.
- zeroinstall.injector.qdom: A quick DOM implementation.
- zeroinstall.injector.reader: Parses an XML feed into a Python representation.
- zeroinstall.injector.run: Executes a set of implementations as a program.
- zeroinstall.injector.sat: Internal implementation of a SAT solver, used by solver.SATSolver.
- zeroinstall.injector.selections: Load and save a set of chosen implementations.
- zeroinstall.injector.solver: Chooses a set of components to make a running program.
- zeroinstall.injector.trust: Records who we trust to sign feeds.
- zeroinstall.injector.writer: Save per-interface and per-feed configuration information.
zeroinstall.support: Useful support routines (for internal use).
- zeroinstall.support.basedir: Support code for the freedesktop.org basedir spec.
- zeroinstall.support.tasks: The tasks module provides a simple light-weight alternative to threads.
zeroinstall.zerostore: Code for managing the implementation cache.
- zeroinstall.zerostore.cli: Code for the 0store command-line interface.
- zeroinstall.zerostore.manifest: Processing of implementation manifests.
- zeroinstall.zerostore.optimise: Optimise the cache.
- zeroinstall.zerostore.unpack: Unpacking archives of various formats.

Classes
	SafeException An exception that can be reported to the user without a stack trace.
	NeedDownload Thrown by injector.autopolicy.AutoPolicy if we tried to start a download and downloading is disabled.

Variables
	version = `'0.49'`
	localedir = `join(dirname(dirname(__file__)), 'locale')`
	translation = `gettext.translation('zero-install', localedir= l...`
	_ = `translation.ugettext` a function for translating strings using the zero-install domain (for use internally by Zero Install)
