# Class for generating signed RPM packages.
#
# Configuration variables used by this class:
# RPM_GPG_PASSPHRASE
#           The passphrase of the signing key.
# RPM_GPG_NAME
#           Name of the key to sign with. May be key id or key name.
# RPM_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.
# RPM_FILE_CHECKSUM_DIGEST
#           Optional variable for specifying the algorithm for generating file
#           checksum digest.
# RPM_FSK_PATH
#           Optional variable for the file signing key.
# RPM_FSK_PASSWORD
#           Optional variable for the file signing key password.
# GPG_BIN
#           Optional variable for specifying the gpg binary/wrapper to use for
#           signing.
# RPM_GPG_SIGN_CHUNK
#           Optional variable indicating the number of packages used per gpg
#           invocation
# GPG_PATH
#           Optional variable for specifying the gnupg "home" directory:
