### speedtest-csv {{SPEEDTEST_CSV_VERSION}}
###
### Usage:
###  speedtest-csv [options]
###
### Options:
###  --header          Display field names (only)
###
###  --header-units    Units (ms, Mbit/s and km) are in header (default)
###  --no-header-units Units are in the values
###  --standardize     Standardize units and number formats (default)
###  --no-standardize  Disable --standardize
###  --share           Generate and provide a URL to the speedtest.net
###                    share results image (default)
###  --no-share        Disable --share
###
###  --quote <str>     Quote fields using <str> (default: none)
###  --sep <str>       Separate fields using <str> (default '\t')
###
###  --help            This help
###  --version         Display version
###
###  --debug           Output extra debug information
###  --last            Use most recent stats, if available
###                    (avoids calling `speedtest-cli`)
###
### Any other options are passed to speedtest-cli as is.
###
### Example:
###  speedtest-csv --header
###  speedtest-csv
###
###  # Defaults in speedtest-csv (<= 1.3.0):
###  speedtest-csv --sep ';' --no-standardize --no-header-units
###
### Installed dependencies:
###  speedtest-cli {{SPEEDTEST_CLI_VERSION}} (https://github.com/sivel/speedtest-cli)
###  python {{PYTHON_VERSION}}
