The reftable format is described in Documentation/technical/reftable.txt. This is a fully reentrant implementation of reading and writing the reftable file format, and should be suitable for embedding in libgit2 too. It does not hook the code up to git to function as a ref storage backend yet. v2: * fold in OpenBSD fixes by Carlo Belón. Han-Wen Nienhuys (19): hash.h: provide constants for the hash IDs reftable: RFC: add LICENSE reftable: add error related functionality reftable: utility functions reftable: add blocksource, an abstraction for random access reads reftable: (de)serialization for the polymorphic record type.
