 Eclipse Platform defines the set of frameworks and common services that
 collectively make up infrastructure required to support the use of Eclipse
 as a component model, as a Rich Client Platform (RCP) and as a comprehensive
 tool integration platform. The core component provides basic platform
 infrastructure that does not involve any UI.
 .
 This package contains the org.eclipse.core.filesystem bundle which provides
 an abstract, generic file system API, including an implementation of this
 API for the local file system. This is the API through which the resources
 plugin accesses an underlying file system.
