I've needed this for myself. I have hundreds, possibly thousands, of snippets of code scattered around my machines, all doing small bits of something. But instead of being able to find the snippet I end up googling around for 10 minutes an re-writing the snippets.

Part of the issue is that some are a snippet, but some are a few folders with a Makefile and some input data etc etc. So maybe I need a meta-snippet format for managing all of this
