[development] Non module contributions

Hi there, I've written a migration tool (to import blog data from a version of Blojsom) which I'd like to make available to anyone who might find it useful. It's a php script designed to be run from the commandline. Is the contributions/tricks/ directory the sort of place I should put this tool, or should I just be hosting it on my own website? It's a tool with pretty limited scope (it does what I needed it to do but no more). So my motivation is to just make sure anyone planning a similar migration can see a previous effort and maybe use it as a starting point, rather than provide a complete off-the-shelf tool which will "Just Work" (tm). Thanks, Ben.
