# Package org.eclipse.equinox.p2.engine

Provides support for interacting with the p2 provisioning engine

## Package Specification

This package specifies API for interacting with the p2 provisioning engine. The engine is a naive service that blindly performs a set of requested changes to a provisioned system. No attempt is made to resolve dependencies or determine whether the resulting system is valid or consistent. It is assumed that the engine client has crafted a valid provisioning plan for the engine to perform, typically by using a planner service.

Since:
  2.0
