# Class for signing package feeds
#
# Related configuration variables that will be used after this class is
# iherited:
# PACKAGE_FEED_PASSPHRASE_FILE
#           Path to a file containing the passphrase of the signing key.
# PACKAGE_FEED_GPG_NAME
#           Name of the key to sign with. May be key id or key name.
# PACKAGE_FEED_GPG_BACKEND
#           Optional variable for specifying the backend to use for signing.
#           Currently the only available option is 'local', i.e. local signing
#           on the build host.
# PACKAGE_FEED_GPG_SIGNATURE_TYPE
#           Optional variable for specifying the type of gpg signature, can be:
#               1. Ascii armored (ASC), default if not set
#               2. Binary (BIN)
#           This variable is only available for IPK feeds. It is ignored on
#           other packaging backends.
# GPG_BIN
#           Optional variable for specifying the gpg binary/wrapper to use for
#           signing.
# GPG_PATH
#           Optional variable for specifying the gnupg "home" directory:
#
