cleaning up some personal projects I worked on in the past months and won't have much time for when my new job starts (Monday):

**cosmo** - a fast command line tool for converting #OSM data into GeoJSON(seq) or parquet.

Another one of those you say? Sure, but this one takes the best of some of the existing tools and combines them into one:
1. speed
2. scale (entire planet with ease on a 16GB laptop)
3. really good data filtering and transformation using YAML.
