Function loadConfig

server/perkeepd/perkeepd.go:139–183

loadConfig returns the server's parsed config file, locating it using the provided arg. The arg may be of the form: - empty, to mean automatic (will write a default high-level config if no cloud config is available) - a filepath absolute or relative to the user's configuration directory, - a URL

(arg string)

//   - a URL
