to have HASH of type HASH-ALGO (a symbol). By default, the file name is the base

name of URL; optionally, NAME can specify a different file name.

This is a simpler version of url-fetch from Guix, that doesn't support mirror://
|
|
or file:// uris. It is specifically designed to prevent substitution of the
|
|
source, for the purpose of downloading copyrighted content you have access to,
|
|
but you don't have the right to redistribute. By marking the derivation as non
|
|
substitutable, this fetch prevents you from giving others access to the source
|
|
if you run a substitute server on your machine."
