github.com/cavaliergopher/grab (go): Package grab provides a HTTP download manager implementation.  Get is the most simple way to download a file:  Get will download the given URL and save it to the given destination directory. The destination filename will be determined automatically by grab using Content-Disposition headers returned by the remote server, or by inspecting the requested URL path.  An empty destination string or "." means the transfer will be stored in the current working directory.  If a destination file already exists, grab will assume it is a complete or partially complete download of the requested file. If the remote server supports resuming interrupted downloads, grab will resume downloading from the end of the partial file. If the server does not support resumed downloads, the file will be retransferred in its entirety. If the file is already complete, grab will return successfully.  For control over the HTTP client, destination path, auto-resume, checksum validation and other settings, create a Client:  You can monitor the progress of downloads while they are transferring:
