  org.activiti.engine | Public API of the Activiti engine. Typical usage of the API starts by the creation of a `ProcessEngineConfiguration` (typically based on a configuration file), from which a `ProcessEngine` can be obtained. Through the services obtained from such a `ProcessEngine`, BPM and workflow operation can be executed: `RepositoryService`: Manages `Deployment`s `RuntimeService`: For starting and searching `ProcessInstance`s `TaskService`: Exposes operations to manage human (standalone) `Task`s, such as claiming, completing and assigning tasks `IdentityService`: Used for managing `User`s, `Group`s and the relations between them `ManagementService`: Exposes engine admin and maintenance operations, which have no relation to the runtime exection of business processes `HistoryService`: Exposes information about ongoing and past process instances. `FormService`: Access to form data and rendered forms for starting new process instances and completing tasks.
  org.activiti.engine.form | Classes related to the `FormService`.
  org.activiti.engine.repository | Classes related to the `RepositoryService`.
