zeuge v0.0.1

zeuge

zeuge (German for "witness") is the basic primitive to build a backward-compatible tracking system for generating unique and universal content identifiers that are hosted through URLs.

zeuge's focus is on making identifier generation (and hence validation) as simple as possible. Anyone on a shell can do it using regular tools and without additional context (e.g. without knowing anything additional about a file's format or encoding).
