If you're going to include backslashes in the string literal then use a
raw string for safety.

1. I'd check whether there's actually a template.
2. 'dict' will accept a list of key/value pairs.
def options(text):
start = text.find('[')
end = text.find(']', start)
if start == -1 or end == -1:
return {}
options = text[start + 1 : end]
return dict(val.split('=') for val in options.split(','))
