" Option to select Python version
" -------------------------------
"
"    python_version_2                       Enable highlighting for Python 2
"                                           (Python 3 highlighting is enabled
"                                           by default). Can also be set as
"                                           a buffer (b:python_version_2)
"                                           variable.
"
"    You can also use the following local to buffer commands to switch
"    between two highlighting modes:
"
"    :Python2Syntax                         Switch to Python 2 highlighting
"                                           mode
"    :Python3Syntax                         Switch to Python 3 highlighting
"                                           mode
