+# 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:
+#
