# DataSift CSDL polygon to radius filter converter by Sergey Vershinin (https://gist.github.com/svershin)

# Takes a CSDL file that has some geo_polygon filters and converts them
# to centroids with an appropriate radius, commenting out the old geo_polygon statements

# *** NOTE: The script expects to have the 'twitter.geo geo_polygon "..."' statement on its own line
# *** BUG ALERT: Have not tested with scripts that have 'GEO_POLYGON' in upper case
