    Ok, I tried the CML2 1.1.0. (Had to spend hours installing Python
    2.0 until I found all required configure options and got the right modules
    compiled in, but ok, that's a one off and is not CML2's fault, also ran
    make test to make sure it works.)

    Installed cml, cwd to kernel, and ran make menuconfig.

    Waited about 2-5 minutes (didn't time it) to get the menu. Slower than
    CML1 by a bit. [Note: My development machine is a Pentium Classic 133S
    with 64MiB ECC RAM and ATA-100 7200RPM HD on Promise ATA-100 controller
    with several network cards, runs like a charm with 2.4 kernel for what it
    is used for: file serving/ftp serving/smb serving/nat]

    In the menu the colour scheme is a bit strange but everyone has a
    different taste. Would need some getting used to, but ok. It does seem
    like a step back in time though, compared to the old menuconfig which had
    nice windows feel and colours, IMHO. I am not sure why it had to be
    changed. Surely you can have the old interface with the new theorem
    prover?

    I found a bug: In "Intel and compatible 80x86 processor options", "Intel
    and compatible 80x86 processor types" I press "y" on "Pentium Classic"
    option and it activates Penitum-III as well as Pentium Classic options at
    the same time!?! Tried to play around switching to something else and then
    onto Pentium Classic again and it enabled Pentium Classic and Pentium
    Pro/Celeron/Pentium II (NEW) this time! Something is very wrong here.

    Now a general comment: CML2 is extremely slow to the point of not being
    usable! )-: It would take me hours to configure a kernel with this. Just
    pressing "n"/"y" or "m" somewhere takes easily several seconds to
    complete... Pressing any of the arrow keys takes between 1 (up/down) and
    10 (left/right) seconds to complete. *Argh!* When a window is up, saying
    press any key to continue there are delays of several seconds of nothing
    happening at all before the window disappers.

    With this slow response time, I wonder whether I actually pressed the key
    so press it again, key gets queued, so it gets executed when the first key
    press has finished executing wreaking havoc. )-: It might be all cool and
    good having a theorem prover and what not inside the configuration but if
    this is going to replace CML1 completely, IMHO, you will _have_ to provide
    some speedy way of configuration (and no, using "vi .config" or equivalent
    is not an option I would like to use...). Many people have been commenting
    that speed doesn't matter "just use a newer computer" but that argument is
    just stupid IMNSHO. That's what MS says when they release a new
    OS/program... I don't need a new computer, this one works absolutely fine
    and maxes out all it's 10Mbit network connections quite happily, so why
    should I buy something faster?!? Just to configure a kernel? Surely not.
    Linux has always been the OS of choice for people with a small budget and
    the way it is going it is running the danger of loosing this corner of
    this rather big market.

    I will be back to CML1 now so I can configure and kick off the compile
    of this kernel before dinner...

    Best regards,

            Anton
