Subject: [rfe] easier customization of kconfig for non-Linux projects
since kconfig is such a nice build system, more projects other than the Linux
kernel have started to integrate it (like uClibc and busybox) ... it'd be nice
if it were easier to customize for each project so that when we pull down the
latest version, we dont have to go through and tweak all of the strings again.
what do you think of something like the attached patch ? i doubt i caught all
the places that'd need to be changed, but this should give a pretty good
picture of what we'd like to have.
