# Summary: Set or show the global Python version
#
# Usage: pyenv global <version>
#
# Sets the global Python version. You can override the global version at
# any time by setting a directory-specific version with `pyenv local'
# or by setting the `PYENV_VERSION' environment variable.
#
# <version> should be a string matching a Python version known to pyenv.
# The special version string `system' will use your default system Python.
# Run `pyenv versions' for a list of available Python versions.
