### This script attempts to download the signature file SHA256SUMS.asc from bitcoin.org
|
|
### It first checks if the signature passes, and then downloads the files specified in
|
|
### the file, and checks if the hashes of these files match those that are specified
|
|
### in the signature file.
|
|
### The script returns 0 if everything passes the checks. It returns 1 if either the
|
|
### signature check or the hash check doesn't pass. If an error occurs the return value is 2
