Introduction
------------

This is a simple archiver, similar to cpio, ar or tar.

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
