This code has been deprecated for a while and confuses the class, lets drop it
and just give the user hard error messages instead of the current warnings/fixups.

-# The following describes deprecated behavior, using any of the
-# following modes will result in a warning, and eventually an error:
-#
-# There are two basic modes supported: 'single update' and 'batch update'
-#
-# 'single update' is used for a single alternative command, and you're
-# expected to provide at least below keywords:
-#
-#     ALTERNATIVE_NAME - the name that the alternative is registered
-#     ALTERNATIVE_PATH - the path of installed alternative
-#
-# ALTERNATIVE_PRIORITY and ALTERNATIVE_LINK are optional which have defaults
-# in this class.
-#
-# 'batch update' is used if you have multiple alternatives to be updated.
-# Unlike 'single update', 'batch update' in most times only require two
-# parameters:
-#
-#     ALTERNATIVE_LINKS - a list of symbolic links for which you'd like to
-#                         create alternatives, with space as delimiter, e.g:
-#
-#         ALTERNATIVE_LINKS = "${bindir}/cmd1 ${sbindir}/cmd2 ..."
-#
-#     ALTERNATIVE_PRIORITY - optional, applies to all
-#
-# To simplify the design, this class has the assumption that for a name
-# listed in ALTERNATIVE_LINKS, say /path/cmd:
-#
-#     the name of the alternative would be: cmd
-#     the path of installed alternative would be: /path/cmd.${BPN}
-#     ${D}/path/cmd will be renamed to ${D}/path/cmd.{BPN} automatically
-#     priority will be the same from ALTERNATIVE_PRIORITY
-#
-# If above assumption breaks your requirement, then you still need to use
-# your own update-alternatives command directly.
 
-# defaults
 ALTERNATIVE_PRIORITY = "10"
