+# Summary: Set or show the global Python version(s)
+#
+# Usage: pyenv global <version> <version2> <..>
+#
+# Sets the global Python version(s). 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> can be specified multiple times and should be a version
+# tag known to pyenv.  The special version string `system' will use
+# your default system Python.  Run `pyenv versions' for a list of
+# available Python versions.
+#
+# Example: To enable the python2.7 and python3.7 shims to find their
+#          respective executables you could set both versions with:
+#
+# 'pyenv global 3.7.0 2.7.15'
+#
