Design goals

• keep key libraries in contrib, protecting provenance and license so that non-technical issues do not keep people from using code
• continue to produce a monolithic contrib build for casual/one-off application consumers
• start building individual libraries within contrib, so that larger apps can manage dependencies in a granular fashion

I propose we start with the new match (matchure) library, get feedback, and then take requests for what other libraries need to be bundled separately.
