Sure, you're welcome!

I think we have to make this more public somehow and somewhere, as
you're the second person asking this in this week :-)

The current grokproject should generate a script


which gives you similar functionality (I didn't use it very often yet,
so I cannot give much more details).

If you don't find the above script in your bin/ directory and if the
grok version you use in your project is fairly recent, then you should
be able to create the debugger by adding a section like this to your

  parts = 

  recipe = z3c.recipe.dev:script
  eggs = sample
  module = grokcore.startup.startup
  method = interactive_debug_prompt
  arguments = zope_conf="${zope_conf:output}"

(where 'sample' would be your project's egg name, of course) and
rerunning ./bin/buildout.

Hm, okay, so I should make that public. It's part of a thing pretentious
called 'The Grok Book' (and which will be renamed to "Notes on Grok"
soon). A grouped collection of experiences with Grok/Zope/Python I am
writing down in (rare) spare-time:

  $ svn co https://svn.gnufix.de/repos/main/grokbook/trunk/ grokbook

It's completely sphinx-driven. The root README.txt tells how to generate
the 'book'. See the (yet rather empty) testing chapter. Comments, etc.
are welcome, of course.

Best regards,
