### Verify SF Binaries ###

This is a legacy SourceForge-era script inherited from upstream and is not used
for DragonX releases. It originally attempted to download a signature file
`SHA256SUMS.asc` from an upstream release host and verify the binaries listed in
it.

For DragonX, release artifacts and checksums are published via the DragonX
project host at https://git.dragonx.is/DragonX and https://dragonx.is . The
script would need to be pointed at those locations before it could be useful; it
is retained here only for historical reference.

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.
