Search for code repositories over many code-hosting services at once.
This means you don't have to mentally filter non-repo results as in regular search engines, but perhaps more importantly, one service does not get prioritized over another in non-transparent ways - they're all equal to one another with HubGrep.
Alpha version - expect breaking changes!
