NAME

src/pmc/packfiledirectory.pmc - PackfileDirectory PMC

DESCRIPTION

This class implements a PackfileDirectory object, a segment of the .pbc data file used for listing the rest of the file's contents. Essentially this segment is a container for all other segments within a Packfile.

See packfile.pmc for the toplevel Packfile interface, see packfilesegment.pmc for the list of common methods every packfile segment pmc must implement; see PDD13 for the design spec.
