Hability to check if a package exists

[lovato]

Is there any way to check if localshop already has a package?
Like the way we can do with pypi.python.org...

Example:

https://pypi.python.org/pypi/surrealism/0.6.0 (ok, and tells there 0.7.0 is the latest)
https://pypi.python.org/pypi/surrealism/0.7.0 (ok, the latest)
https://pypi.python.org/pypi/surrealism/0.7.1 (HTTP 404)

This way I can use a script to determine if I can upload a newer package or not. If there is a match, I gave the user an error.

If there is not such feature, I can help develop it.
