1	bbs_meta_regions(bbs_dir = bbs_ftp(), zip_files = FALSE)

`bbs_dir`	Directory from which to get data. Defaults to the USGS FTP directory for the most recent BBS release. May alternatively be a path to a local directory, or ftp address for an older BBS release.
`zip_files`	Include names of zip files containing 10-stop and 50-stop data? Defaults to FALSE.

`country_num`	integer code for country
`country_name`	name of country
`state_num`	integer code for state/province/territory
`state_name`	name of state/province/territory

If zip_files = TRUE, also includes the column:

`ten_stop_file`	name of zip file with 10-stop survey data (or `NA` if region does not have a zip file)
