The PyPA recommended tool for installing and managing Python packages.
pip is a replacement for easy_install. It uses mostly the same techniques
for finding packages, so packages that were made easy_installable should
be pip-installable as well.
pip is meant to improve on easy_install. Some of the improvements:
* All packages are downloaded before installation. Partially-completed
installation doesn't occur as a result.
* Care is taken to present useful output on the console.
* The reasons for actions are kept track of. For instance, if a package
is being installed, pip keeps track of why that package was required.
* Error messages should be useful.
* Packages don't have to be installed as egg archives, they can be
installed flat (while keeping the egg metadata).

============================== !!!! WARNING !!!! ==========================
pip MUST ONLY be used:
* With the --user flag, OR
* To install or manage Python packages in virtual environments
Failure to follow this warning can and will result in an inconsistent
system-wide Python environment (LOCALBASE/lib/pythonX.Y/site-packages) and
cause errors.
Avoid using pip as root unless you know what you're doing.
============================== !!!! WARNING !!!! ==========================
Convert Python ports to FLAVORS.
Ports using USE_PYTHON=distutils are now flavored. They will
automatically get flavors (py27, py34, py35, py36) depending on what
versions they support.
There is also a USE_PYTHON=flavors for ports that do not use distutils
but need FLAVORS to be set. A USE_PYTHON=noflavors can be set if
using distutils but flavors are not wanted.
A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
added to cope with Python ports that did not have the Python
PKGNAMEPREFIX but are flavored.
USES=python now also exports a PY_FLAVOR variable that contains the
