That does seem nicer. The load error messages from gems can
be rather
unhelpful. Is this what you used to debug your friends
problem? Just
want to know how much of a beating to give it for testing
purposes.

That's a nice idea too. If/when we get any more generators.

Thanks,

well, no, I just commented out the rescue..
Anyway this was just a suggestion and this is the reason
I've not 
provided it as a patch+tests, but it /seem/ to work with the
sources 
from repo.nitroproject.org:

$ ruby gen/bin/gen app foo
Cannot load the specified generator!
         unmet dependency loading gen/app/gen.rb:
         Could not find RubyGem facets (= 1.0.3)

$ gem install facets
<snip>

$ruby gen/bin/gen app

NAME
      gen app - Nitro application generator.
<snip>

$ ruby gen/bin/gen ap
Cannot load the specified generator!
         no such generator "ap"

and withouth -rubygems

$ ruby gen/bin/gen app
Cannot load the specified generator!
         unmet dependency loading gen/app/gen.rb:
         no such file to load -- facet/dir/self/recurse

Oh, please be hard with it, I just quickly tested on a win32
box, which 
is Evil(TM)
