				# Gitian Downloader

				## Download config

				Construct a download config:

				---
				signers:
				BF6273FAEF7CC0BA1F562E50989F6B3048A116B5:
				weight: 20
				name: Devrandom
				key: devrandom
				minimum_weight: 30

				The keys can be extracted with:

				gpg --export-options export-minimal --export KEYID

				and saved into devrandom-key.pgp (see "key" in signers).

				The long key id can be obtained with:

				gpg --status-fd 1 --dry-run --import KEYFILE

				## ZIP file

				The zip file should have the payload produced in build/out by gbuild, plus a gitian directory. The gitian directory should contain files of the form:

				devrandom-build.assert
				devrandom-build.assert.pgp

				where the FILE.assert file is the PACKAGE-res.yml build report and the .pgp file is signature.pgp generated by gsign.

				## Running the downloader

				gitian-updater --url file:///tmp/PACKAGE.zip --config PACKAGE-download-config --dest DEST

				Of course, the URL can be external rather than on the file system.
