IMO the main points/questions are:
- where to document the command-line options and environment variables
(including the recent KCONFIG_CONFIG): in a usage() function or in
Documentation/kbuild/usage.txt file?
- if the answer above is in a usage() function, how does a user invoke
that help request? Doing "make config -h" doesn't work: 'make' sees
the -h and spits out its own help text. Would a special case of
'make config help' be acceptable or is this a good reason to use
a usage.txt file instead?
- or have you already taken care of all of this? 8;)
Thanks.
