This plugin allows sharding a spec repo's
Specs directory to be more performant under various
git operations. By sharding a repository, a large amount of specs can be stored at logarithmic cost, rather than linear cost. Most private specs repos will never have to be concerned with the particular performance characteristics of git, but the master specs repo is large enough that sharding will bring a massive performance gain.
