Documentation

Overview

Package zip contains a fork of archive/zip reader.

This package copies logic from archive/zip to read the central directory file header from the end of a ZIP file. The only modification is that readDirectoryEnd() is exported as ReadZIPOffset(), returning the position of the start of the ZIP contents.

See https://go.dev/issues/10464

This package MUST NOT be depended on by external code and may change at any time. This is not an "internal" package only because we're required to place external code under a top level "third_party/" directory.
