libCUDF - CUDF (Common Upgradeability Description Format) library
=================================================================
libCUDF is a reference implementation of CUDF (Common Upgradeability
Description Format), a document format to describe package upgrade scenarios,
in a package manager agnostic way. distributions.
A CUDF document consists of an optional leading "preamble", a "package
universe", and a trailing "user request":
- The package universe describes all packages known to the package
manager, a subset of which (the "package status") denotes the
package being currently installed on a given machine.
- The user request denotes a change to the package status requested by
the user, e.g.: "install package foo", "remove package bar", ...
- The preamble contains meta-information such as a typing information
for custom package properties, checksums, document unique
identifiers, ...
A CUDF document is naturally complemented by a "solution" describing
the resulting package status (if any) that satisfies the user request,
as found by a package manager.
libCUDF enables manipulation of CUDF and related documents.
Development
