Download accelerator that supports fetching a file from multiple sources concurrently.

• Docker
• Docker Compose
• Make

i.e., no need to have Go installed locally

$ make deps

$ make fmt

$ make test

$ make build target={target OS}

• generates msdl inside bin/ directory
• possible values for target can be found here
• example: make build target=linux

Running msdl (after generating it using make build):

msdl [flags...] [space-delimited URLs...]

$ ./msdl -f destfile.txt http://source1.com/a.txt http://source2.com/a.txt http://source3.com/a.txt

• downloads a.txt from 3 different sources concurrently and saves it to a local file named destfile.txt
• note: the filenames can be different in the sources as long as they are effectively the same file
