+#        pyenv install -l|--list
+#        pyenv install --version

+#   -l/--list          List all available versions
+#   -f/--force         Install even if the version appears to be installed already
+#   -s/--skip-existing Skip if the version appears to be installed already
+#
+#   python-build options:

+#   -k/--keep          Keep source tree in $PYENV_BUILD_ROOT after installation

+#   -p/--patch         Apply a patch from stdin before building
+#   -v/--verbose       Verbose mode: print compilation status to stdout
+#   --version          Show version of python-build
+#   -g/--debug         Build a debug version
