# Class for generating signed IPK packages.
#
# Configuration variables used by this class:
# IPK_GPG_PASSPHRASE_FILE
#           Path to a file containing the passphrase of the signing key.
# IPK_GPG_NAME
#           Name of the key to sign with.
# IPK_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.
# IPK_GPG_SIGNATURE_TYPE
#           Optional variable for specifying the type of gpg signatures, can be:
#                     1. Ascii armored (ASC), default if not set
#                     2. Binary (BIN)
# GPG_BIN
#           Optional variable for specifying the gpg binary/wrapper to use for
#           signing.
# GPG_PATH
#           Optional variable for specifying the gnupg "home" directory:
#
