Huh, I have a todo item to write the old 2.6.12 snapshot of kconfig I have in http://landley.net/toybox (it's the only gpl code left in the build), but I just got finished _removing_ python as a bulid dependency last year and am reluctant to reintroduce it. I gave up trying to patch upstream kconfig after a half-dozen rounds of https://lwn.net/Articles/161086/ and such were all ignored. (I just documented http://landley.net/aboriginal/FAQ.html#dev_miniconfig and went on with my life. Yes, still using miniconfig.sh a decade later...) (I have rather elaborate kconfig parsing to extract help text, I use specially formatted menuconfig help entries to create command help, and merge the sub-options to create a unified usage: line and alphabetically sorted option description list. That's the stuff that used to be python, which I rewrote in C last year. Somebody submitted a kconfig parser written in awk to toybox a couple years ago, but I can't maintain awk...)
