Same as Jack. But I also try to keep things as self-contained and independent as possible as I move through the stages. That way, if I need to share something with another project, I can just copy-paste the contents of a single file. I much prefer that to the overhead of formal dependency systems. Given the choice between a cluster of packaging / metadata files, a full repo, etc. versus a single file that I can copy around but any changes I make aren't cleanly tracked, I often prefer the ergonomics of the latter.
