    help

      If you set this to Y, then you will be able to try very experimental

      features.

      Experimental features can be one of:

        - working, in which case you should tell me it is!

        - buggy, in which case you could try patching and send me the result

        - unfinished, in which case you could try hacking it and send me the result

        - non-existant, in which case you could also try hacking it in and send the result

config OBSOLETE

    bool

    prompt "Use obsolete features"

    default n

    help

      If you set this to Y, you will be able to select obsolete features.

      Such obsolete features are the use of old kernel headers, old

      gcc versions, etc...

    help

      If you say 'y' here, then you will be able to restart crosstool-NG at

      any step.

      It is not currently possible to rstart at any of the debug facility.

      They are treated as a whole.

      See docs/overview.txt for the list of steps.

config DEBUG_CT_SAVE_STEPS_GZIP

    bool

    default y

    depends on DEBUG_CT_SAVE_STEPS

    help

      If you are tight on space, then you can ask to gzip the saved states

      tarballs. On the other hand, this takes some longer time...

      To lose as less time as possible, the gzip process is done with a low

      compression ratio (-3), which gives roughly 70% gain in size. Going

      further doesn't gain much, and takes far more time (believe me, I've

      got figures here! :-) ).

    help

      Number of jobs make will be allowed to run concurently.

      Set this higher than the number of processors you have, but not too high.

      A good rule of thumb is twice the number of processors you have.

      Enter 1 (or 0) to have only one job at a time.

config LOAD

    int

    prompt "Maximum allowed load"

    default 0

    help

      Specifies that no new jobs should be started if there are others jobs

      running and the load average is at least this value.

      Makes sense on SMP machines only.

      Enter 0 to have no limit on the load average.

      Note: only the integer part of the load is allowed here (you can't enter

            0.75 for example).

config NICE

#      Normally, you would set this to ${CT_PREFIX_DIR}, but if for some reasons

#      you can't write there, you can install somewhere else and have a third

#      person do the install for you.

#      The reason you might also want to install elsewhere is if you are going

      Don't apply patches coming with CT-NG, only those patches available in

      first, and then your patches.

      Treat warnings from the different tools as crosstool-ng warnings.

      If you say 'y' here, then those warnings will be prefixed with

      '[WARN ]' instead of the default '[ALL  ]'.

      You can safely say 'n' here. Those warnings will anyway be

      recorded in the log file (provided you configured one).

      Tools error will always be logged as crosstool-ng errors.

      If you say 'y' here, you'll be able to see the elapsed time.

      As a bonus, you'll also get a rotating bar (/-\|) showing you

      that the build is not stalled (the bar rotates 1/4 every 10 lines

      of components build log).

      Note that the elapsed time can stall for a little while if a

      component has long commands, as the elapsed time is only updated

      each line.

      Save *full* logs to a file. Even log levels you didn't specify above

      will be available in this file. The log file will be named build.log

      and stored in the toolchain prefix dir (set above).

      As a bonus, there is a script in tools/extractConfig.sh that is able

      to extract the configuration of crosstool-NG from the log file.

      Definitely, say Y.

config LOG_FILE_COMPRESS
