Checking integrity

Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this:

gpg --verify gnuastro-0.4.tar.gz.sig

If that command fails because you don't have the required public key, then run this command to import it:

gpg --keyserver --recv-keys 16A8A4B2AEC42AFF

and rerun the 'gpg --verify' command.
