Currently, as Thomas pointed out [0], the help for kconfig packages is
not consistently used and handled by the different packages.
This commit introduces a generic help text for kconfig packages, that is
based on what the package declares:
- the list of kconfig editors it supports;
- whether it is possible to save back the configuration (impossible if
the package uses an in-tree defconfig file);
- whether the package actually supports (loading and saving) defconfig
files, by introducing a new variable a package can set if it does
not (only busybox is known to be in that case).
That new help helper is only used if the package does not already define
its own help, to be consistent with what we do for other _CMDS.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
