I just installed Python 3.4.2 on Windows and noticed that its Scripts
directory has these files out-of-the-box:

easy_install.exe
easy_install-3.4.exe.
pip.exe
pip3.exe
pip3.4.exe

Based on Nick's explanation above, having pip.exe there looks like bug
in the installer and could easily cause a conflict with other pip
installations. I don't understand why easy_install is included there
in the first place, but easy_install.exe can obviously cause a similar
conflict.
