Okay, how would this work then; I fancy having a look. You'd need to
specify a list of modules to exclude from the grokking process. This
could be either an exhaustive list:

<grok:grok package="foo">
   <grok:exclude_module module="me" />
   <grok:exclude_module module="grok" />
   ...
</ grok:grok>

or maybe something more general:

<grok:grok package="bar">
   <grok:exclude_pattern expr="^f?tests$" />
</ grok:grok>

or both:

<grok:grok package="xyz">
   <grok:exclude_module module="me" />
   <grok:exclude_module module="grok" />
   <grok:exclude_pattern expr="^f?tests$" />
</ grok:grok>

or perhaps more simply:

<grok:grok package="baz" exclude_modules="some;delim;separated;list" />

or something I haven't thought of?

Secondly, we have already mentioned issue of wanting to specify
specific modules (rather than any module/package matching a name). My
immediate idea was that if the package was preceeded by a dot, then it
was relative to the package root:

<grok:grok package="faz" exclude_modules=".tests.grokkers" />

Although this may introduce complexities regarding the recursive
nature of the scanning algorithm.
