+# Summary: Set or show the local application-specific Python version(s)
+#
+# Usage: pyenv local [-f|--force] [<version> [...]]
+#        pyenv local --unset
+#
+#   -f/--force    Do not verify that the versions being set exist
+#
+# Sets the local application-specific Python version(s) by writing the
+# version name to a file named `.python-version'.
+#
+# When you run a Python command, pyenv will look for a `.python-version'
+# file in the current directory and each parent directory. If no such
+# file is found in the tree, pyenv will use the global Python version
+# specified with `pyenv global'. A version specified with the
+# `PYENV_VERSION' environment variable takes precedence over local
+# and global versions.
+#
+# <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 local 3.7.0 2.7.15'
