	// This script will process a planet file and collect frequently occuring tags that we care about.
	// It produces files containing all the top names and tags: `dist/collected/names_all.json`
	//
	// `names_all.json` contains a dictionary object in the format:
	// "key/value|name": count
	// "amenity/cafe|Starbucks": 159

(This is the first time I run it, because I saw that tas50 has not uploaded collected data for several weeks(sorry. just found commits uploaded 1 hours ago: 0ef28f5), so I want to try it myself, so I meet with those kind of error.)

Because I am worried that the files in dist will affect the result, in order to "clean run" during operation, I deleted the /dist folder

If can't find {what}_all.json, is it okay to create one at this situation?

In other words, if the existing file must be used, why not prompt at the beginning of the operation but report an error after the time consuming collection is completed?
