Lightweight Archiver: lar ----------------------- Table of Contents - Introduction - Usage - Archive format - TODO - Copyright and License Introduction ------------ This is a simple archiver, similar to cpio, ar or tar. It was designed and written for coreboot. Design goals were - minimum overhead - maximum fault tolerance - simplicity For a usage example see example.c. For questions contact Stefan Reinauer <stepan@coresystems.de>. Usage ----- Create archive archive.lar containing files file1 ... fileN: $ lar c archive.lar file1 ... fileN Extract files from archive.lar: $ lar x archive.lar [file1 ... fileN] List files in archive: $ lar l archive.lar Archive format -------------- The rough format is: |--------------| | header | |--------------| | data | |--------------| | header | |--------------| | data | |--------------| ... Headers have to be 16 byte aligned. |----------------------------| | magic (8 bytes) | |----------------------------| | length (4 bytes) | |----------------------------| | checksum (4 bytes) | |----------------------------| | offset to blob (4 bytes) | |----------------------------| | "path name" | <-- null terminated, aligned to 16 bytes |----------------------------| | blob (aligned to 16 bytes) | |----------------------------| TODO ---- - Reading flash layouts - This does not enforce any alignment yet - Alignment enforcing will be optional Copyright and License --------------------- Copyright (C) 2006-2007 coresystems GmbH Written by Stefan Reinauer <stepan@coresystems.de> for coresystems GmbH.
