* `go run main.go download [-n <count>]`: download and save all translations.
`n` is optional flag where count is a number of concurrent downloads.
* `go run ./scripts/translations download [-n <count>]`: download and save
all translations. `n` is optional flag where count is a number of
concurrent downloads.
* `go run main.go upload`: upload the base `en` locale.
* `go run ./scripts/translations upload`: upload the base `en` locale.
* `go run main.go summary`: show the current locales summary.
* `go run ./scripts/translations summary`: show the current locales summary.
* `go run main.go unused`: show the list of unused strings.
* `go run ./scripts/translations unused`: show the list of unused strings.
* `go run main.go auto-add`: add locales with additions to the git and
restore locales with deletions.
* `go run ./scripts/translations auto-add`: add locales with additions to the
git and restore locales with deletions.
After the download you'll find the output locales in the `client/src/__locales/`

example `ar be bg`.
* `UPLOAD_LANGUAGE`: set an alternative language for `upload`.
