Static Public Member Functions
static string	ToPackageName (string name)
	Derive a package name for a resource. The package name returned by this method may not be a legal package name. This method returns null if the resource name ends with a "/" (a directory) or the resource name does not contain a "/".
static string	ToResourceName (string dir, string file)
	Returns a resource name corresponding to the relative file path between dir and file . If the file is a directory then the name will end with a "/", except the top-level directory where the empty string is returned.
static ? string	ToFilePath (string dir, string name)
	Returns a file path to a resource in a file tree. If the resource name has a trailing "/" then the file path will locate a directory. Returns null if the resource does not map to a file in the tree file.
