# Bash script to fetch villages data in Mali
#  - fetched as several .osm files for different data types
#  - merged into one using osmconvert
#  - centroid nodes only using osmconvert
#  - converted to CSV using osmconvert
#
#  ...but the whole thing couldve been done by Overpass

#These steps can actually be done as
# one magical OverpassAPI query.
