* **Depending on Python itself.** pyenv was made from pure shell scripts.
There is no bootstrap problem of Python.
* **Need to be loaded into your shell.** Instead, pyenv's shim

* **Have a configuration file.** There's nothing to configure except
which version of Python you want to use.
* **Manage virtualenv.** Of course, you can create [virtualenv](http://pypi.python.org/pypi/virtualenv)
yourself, or [python-virtualenv](https://github.com/yyuu/python-virtualenv)
to automate the process.
* **Prompt you with warnings when you switch to a project.** Instead
of executing arbitrary code, pyenv reads just the version name
from each project. There's nothing to "trust."
