Usage: #{__FILE__} file_or_URI(s) ...
This utility outputs GNSS data specified with file_or_URI(s).
A file_or_URI having additional ".gz" or ".Z" extension is recognized as a compressed file, and the decompression is performed before output.
In addition to a local file, major URIs such as http(s)://..., ftp://..., and ntrip:// are supported.
Serial port (COMn for Windows, /dev/tty* for *NIX) is also acceptable as an input file name.
