want to get package documentation from pip without installing

[Skaperen]

way back when i was getting started with Python i saw the specs of a DNS query library the would let me do any kind of DNS query including setting any flags and specifying which DNS server the query goes to. it looked good enough to put together a recursive lookup in Python without having to deal with any packet level or byte level stuff. it would parse the packets coming back and make everything easy to access. it supported UDP and TCP, IPv4 and IPv6. it looked to be very complete and something that could eventually be very useful.

i originally thought it was part of the Python library, but i can't find it in the docs at all. a pip search yields lot of stuff. but, the descriptions don't give me any idea of what each package really covers. is there a way to just download (not install) various packages so maybe i can figure out if any of these is what i really want.
