Download a URL's content and copy it to the destination without saving

it in temporary storage.

Setting --auto-filename will cause the file name to be retreived from

|
the from URL (after any redirections) and used in the destination

path.

|
Setting --no-clobber will prevent overwriting file on the

destination if there is one with the same name.

Setting --stdout or making the output file name "-" will cause the
|
|
output to be written to standard output.
