"Single-threaded downloading has its benefits, especially when
Wget is concerned. Other download managers have internal databases
to help them keep track of which parts of files are already
downloaded. Wget gets this information simply by scanning a file's
size. This means that Wget is able to continue downloading a file
which another application started to download; most other download
managers lack this feature. Usually I start by downloading a file
with my browser, and if it is too large, I stop downloading and
finish it later with Wget."
