what pip has internally already (i.e. literally in it's package namespace): - pypi crawling/downloading - wheel installing (does not require the pypi wheel project; only building wheels requires that) what pip has "bundled' already: - distlib (in 'pip.vendor'; currently only used for some --pre version logic) what pip still needs to be self-sufficient to do wheel installs: - something bundled or internal that does what pkg_resources does theoretical options: 1) bundle setuptools/pkg_resources 2) use the bundled distlib to replace our use of pkg_resources 3) internalize pkg_resources as pip.pkg_resources (i.e. fork off pkg_resources) Marcus
