devpi-server-0.8.4: using pip's link parser now

[holger krekel]

hi all,

devpi-server, the self-updatding pypi.python.org caching proxy,
just saw a new 0.8.4 release. Instead of BeautifulSoup it now
uses pip's link parsing. This should serve as a shortcut to avoid
real life crawling issues. IOW, whatever pip can install, should
also be installable through the devpi-server cache.

More info, getting started, deployment info on devpi-server:

http://pypi.python.org/pypi/devpi-server

thanks to Markus Zapke-Gruendemann for cleaning up some internals.

cheers,
holger
