- Feed files
This document is a formal description of the XML feed file format. An interface describes a program,
library or other component. A feed provides a list of known implementations of the interface (versions of the program)
and details about how to get them, how to check that they are authentic, how to run them and what other components
they depend on.
- Selections files
This document describes the format of 0install's XML selections documents. A
selections document contains all the information needed to launch a program.
0install generates a selections document by collecting information from
multiple feeds and then running a solver to choose the best combination of
- Manifest files
Zero Install implementations are directory trees identified by an
algorithm name (e.g., "sha1"), and digest of their contents calculated using
that algorithm. Adding, deleting, renaming or modifying any file in a tree will
change its digest. It should be infeasibly difficult to generate a new tree
with the same digest as a given tree. Thus, if you know the digest of the
implementation you want, and someone gives you a tree with that digest, you can
trust that it is the implementation you want. This document describes how a
digest is calculated from a directory tree.
