This is a small, high-quality storage engine for saving files into, and retrieving files out of permanent ISO 28500 compliant WARC silos.

This is only an storage engine, it supports little more than the two operations "store this" and "get that", all the other aspects of a proper bit-archive, access control, user interfaces, data validation and so on must be provided elsewhere.

Each stored file gets assigned a WARC-Record-ID. WARC records of type "resource" uses the SHA256 sum of the stored file, and WARC "metadata" records uses the SHA256 of the "WARC-Refers-To:" header and the metadata file content.

An auxillary rebuildable index facilitates rapid access to individual stored objects keyed by the WARC-Record-ID.

Almost the entire focus during development has been on correctness and robustness, and presently FreeBSD is the only supported platform, but porting it to other UNIX-like operating systems is expected to require a trivial effort. (Patches/Pulls are welcome).

One "test-application" called "stow" is built in, it makes very neat deduplicated permanent personal archive. In compliance with the "dogfood" principle, I have all 217 Gigabytes of my personal archive stored with "stow".
