+" (``ln -s <this file> ~/.vimrc``).  All options are protected by autocmds
+" (read below for an explanation of the command) so blind sourcing of this file

+" Only basic settings needed to enforce the style guidelines are set.

+" Python: 4 spaces

+"    'textwidth'
+" - o : do not insert the comment leader when using 'o' or 'O' from command mode

+" The following section contains suggested settings.  While in no way required
+" to meet coding standards, they are helpful.
+
+" Set the default file encoding to UTF-8: ``set encoding=utf-8``
+
+" Puts a marker at the beginning of the file to differentiate between UTF and
+" UCS encoding (WARNING: can trick shells into thinking a text file is actually
+" a binary file when executing the text file): ``set bomb``
+
+" For full syntax highlighting:
+"``let python_highlight_all=1``
+"``syntax on``
+
+" Automatically indent based on file type: ``filetype indent on``
+" Keep indentation level from previous line: ``set autoindent``
+
+" Folding based on indentation: ``set foldmethod=indent``
