Oh, OK. If that's all you did, that shouldn't pose a problem.

I believe that's what Phillip's recent changes have been about. They
provide a way to put the egg metadata inside the package directory so
that it can install like a traditional package but still have the
appropriate metadata. I'll stop commenting at this point, though,
because Phillip's the authoritative source and I've never had to
personally walk down the path of packaging an egg up into something

During runtime. Certain parts of TurboGears can be extended just by
installing an egg with the additional functionality. TurboGears itself
uses this mechanism to define the base pieces. (tg-admin commands are
an example of this: anyone can create an egg that adds tg-admin
commands. the existing commands are all defined in the same way that a
user would create commands.)
