  Sort of.  You can run the ~gnb/bin/update-web shell script, but
because of the cheap&nasty way I wrote it there some problems with
permissions if anyone other than me does it.  Fixing this is somewhere
on the TODO list...

  Your documentation is very good...easy to read, accurate and up-to-date.
Well, mostly, I've got a few comments (see below).  Actually I was wondering
if I could basically subsume large chunks of it into the FAQ (with full credit
of course!) ?  The idea is that someone could print out the FAQ and have
almost all the info they need in one document.  Given the current state of
the FAQ it needs a major clue-transfusion.

  Anyway, my comments on gdb.php:

1.  "Note 'GDB Stub kernel debug' and 'Early printk support' are mutually
     exclusive."  AFAICT this is not true, at least it's not supposed to be.
     If something in the code or doco suggests that, I need to fix it!

2.   In the 3rd-last paragraph, it talks about the stub detaching from 
     the host gdb.  Perhaps it might be a good idea to mention the
     message gdb gives, which is probably quite confusing for newbies.

  BTW when building a debugging kernel, has anyone tried removing the
-fomit-frame-pointer flag from the compile?  I believe this will enable
gdb to show a kernel stack trace.  The ARM port has a config variable,
CONFIG_FRAME_POINTER, to do this.
